-Equal returns true iff protocol buffers a and b are equal.
-The arguments must both be pointers to protocol buffer structs.
-
-Equality is defined in this way:
-  - Two messages are equal iff they are the same type,
-    corresponding fields are equal, unknown field sets
-    are equal, and extensions sets are equal.
-  - Two set scalar fields are equal iff their values are equal.
-    If the fields are of a floating-point type, remember that
-    NaN != x for all x, including NaN. If the message is defined
-    in a proto3 .proto file, fields are not "set"; specifically,
-    zero length proto3 "bytes" fields are equal (nil == {}).
-  - Two repeated fields are equal iff their lengths are the same,
-    and their corresponding elements are equal. Note a "bytes" field,
-    although represented by []byte, is not a repeated field and the
-    rule for the scalar fields described above applies.
-  - Two unset fields are equal.
-  - Two unknown field sets are equal if their current
-    encoded state is equal.
-  - Two extension sets are equal iff they have corresponding
-    elements that are pairwise equal.
-  - Two map fields are equal iff their lengths are the same,
-    and they contain the same set of elements. Zero-length map
-    fields are equal.
-  - Every other combination of things are not equal.

-Package proto converts data structures to and from the wire format of
-protocol buffers.  It works in concert with the Go source code generated
-for .proto files by the protocol compiler.
-
-A summary of the properties of the protocol buffer interface
-for a protocol buffer variable v:
-
-  - Names are turned from camel_case to CamelCase for export.
-  - There are no methods on v to set fields; just treat
-	them as structure fields.
-  - There are getters that return a field's value if set,
-	and return the field's default value if unset.
-	The getters work even if the receiver is a nil message.
-  - The zero value for a struct is its correct initialization state.
-	All desired fields must be set before marshaling.
-  - A Reset() method will restore a protobuf struct to its zero state.
-  - Non-repeated fields are pointers to the values; nil means unset.
-	That is, optional or required field int32 f becomes F *int32.
-  - Repeated fields are slices.
-  - Helper functions are available to aid the setting of fields.
-	msg.Foo = proto.String("hello") // set field
-  - Constants are defined to hold the default values of all fields that
-	have them.  They have the form Default_StructName_FieldName.
-	Because the getter methods handle defaulted values,
-	direct use of these constants should be rare.
-  - Enums are given type names and maps from names to values.
-	Enum values are prefixed by the enclosing message's name, or by the
-	enum's type name if it is a top-level enum. Enum types have a String
-	method, and a Enum method to assist in message construction.
-  - Nested messages, groups and enums have type names prefixed with the name of
-	the surrounding message type.
-  - Extensions are given descriptor names that start with E_,
-	followed by an underscore-delimited list of the nested messages
-	that contain it (if any) followed by the CamelCased name of the
-	extension field itself.  HasExtension, ClearExtension, GetExtension
-	and SetExtension are functions for manipulating extensions.
-  - Oneof field sets are given a single field in their message,
-	with distinguished wrapper types for each possible field value.
-  - Marshal and Unmarshal are functions to encode and decode the wire format.
-
-When the .proto file specifies `syntax="proto3"`, there are some differences:
-
-  - Non-repeated fields of non-message type are values instead of pointers.
-  - Enum types do not get an Enum method.
-
-The simplest way to describe this is to see an example.
-Given file test.proto, containing
-
-	package example;
-
-	enum FOO { X = 17; }
-
-	message Test {
-	  required string label = 1;
-	  optional int32 type = 2 [default=77];
-	  repeated int64 reps = 3;
-	  optional group OptionalGroup = 4 {
-	    required string RequiredField = 5;
-	  }
-	  oneof union {
-	    int32 number = 6;
-	    string name = 7;

-// The definition of "enclosing" used by this function considers
-// additional whitespace abutting a node to be enclosed by it.
-// In this example:
-//
-//              z := x + y // add them
-//                   <-A->
-//                  <----B----->
-//
-// the ast.BinaryExpr(+) node is considered to enclose interval B
-// even though its [Pos()..End()) is actually only interval A.
-// This behaviour makes user interfaces more tolerant of imperfect
-// input.
-//
-// This function treats tokens as nodes, though they are not included
-// in the result. e.g. PathEnclosingInterval("+") returns the
-// enclosing ast.BinaryExpr("x + y").
-//
-// If start==end, the 1-char interval following start is used instead.
-//
-// The 'exact' result is true if the interval contains only path[0]
-// and perhaps some adjacent whitespace.  It is false if the interval
-// overlaps multiple children of path[0], or if it contains only
-// interior whitespace of path[0].
-// In this example:
-//
-//              z := x + y // add them
-//                <--C-->     <---E-->
-//                  ^
-//                  D

-// z-assignment statement, because it spans three of its children (:=,

-
-// This file handles cgo preprocessing of files containing `import "C"`.
-//
-// DESIGN
-//
-// The approach taken is to run the cgo processor on the package's
-// CgoFiles and parse the output, faking the filenames of the
-// resulting ASTs so that the synthetic file containing the C types is
-// called "C" (e.g. "~/go/src/net/C") and the preprocessed files
-// have their original names (e.g. "~/go/src/net/cgo_unix.go"),
-// not the names of the actual temporary files.
-//
-// The advantage of this approach is its fidelity to 'go build'.  The
-// downside is that the token.Position.Offset for each AST node is
-// incorrect, being an offset within the temporary file.  Line numbers
-// should still be correct because of the //line comments.
-//
-// The logic of this file is mostly plundered from the 'go build'
-// tool, which also invokes the cgo preprocessor.
-//
-//
-// REJECTED ALTERNATIVE
-//
-// An alternative approach that we explored is to extend go/types'
-// Importer mechanism to provide the identity of the importing package
-// so that each time `import "C"` appears it resolves to a different
-// synthetic package containing just the objects needed in that case.
-// The loader would invoke cgo but parse only the cgo_types.go file
-// defining the package-level objects, discarding the other files
-// resulting from preprocessing.
-//
-// The benefit of this approach would have been that source-level
-// syntax information would correspond exactly to the original cgo
-// file, with no preprocessing involved, making source tools like
-// godoc, guru, and eg happy.  However, the approach was rejected
-// due to the additional complexity it would impose on go/types.  (It
-// made for a beautiful demo, though.)
-//
-// cgo files, despite their *.go extension, are not legal Go source
-// files per the specification since they may refer to unexported
-// members of package "C" such as C.int.  Also, a function such as
-// C.getpwent has in effect two types, one matching its C type and one
-// which additionally returns (errno C.int).  The cgo preprocessor
-// uses name mangling to distinguish these two functions in the
-// processed code, but go/types would need to duplicate this logic in
-// its handling of function calls, analogous to the treatment of map
-// lookups in which y=m[k] and y,ok=m[k] are both legal.

-//
-//
-// CONCEPTS AND TERMINOLOGY
-//
-// The WORKSPACE is the set of packages accessible to the loader.  The
-// workspace is defined by Config.Build, a *build.Context.  The
-// default context treats subdirectories of $GOROOT and $GOPATH as
-// packages, but this behavior may be overridden.
-//
-// An AD HOC package is one specified as a set of source files on the
-// command line.  In the simplest case, it may consist of a single file
-// such as $GOROOT/src/net/http/triv.go.
-//
-// EXTERNAL TEST packages are those comprised of a set of *_test.go
-// files all with the same 'package foo_test' declaration, all in the
-// same directory.  (go/build.Package calls these files XTestFiles.)
-//
-// An IMPORTABLE package is one that can be referred to by some import
-// spec.  Every importable package is uniquely identified by its
-// PACKAGE PATH or just PATH, a string such as "fmt", "encoding/json",
-// or "cmd/vendor/golang.org/x/arch/x86/x86asm".  A package path
-// typically denotes a subdirectory of the workspace.
-//
-// An import declaration uses an IMPORT PATH to refer to a package.
-// Most import declarations use the package path as the import path.
-//
-// Due to VENDORING (https://golang.org/s/go15vendor), the
-// interpretation of an import path may depend on the directory in which
-// it appears.  To resolve an import path to a package path, go/build
-// must search the enclosing directories for a subdirectory named
-// "vendor".
-//
-// ad hoc packages and external test packages are NON-IMPORTABLE.  The
-// path of an ad hoc package is inferred from the package
-// declarations of its files and is therefore not a unique package key.
-// For example, Config.CreatePkgs may specify two initial ad hoc
-// packages, both with path "main".
-//
-// An AUGMENTED package is an importable package P plus all the
-// *_test.go files with same 'package foo' declaration as P.
-// (go/build.Package calls these files TestFiles.)
-//
-// The INITIAL packages are those specified in the configuration.  A
-// DEPENDENCY is a package loaded to satisfy an import in an initial
-// package or another dependency.
-//
-package loader
-
-// IMPLEMENTATION NOTES
-//
-// 'go test', in-package test files, and import cycles
-// ---------------------------------------------------
-//
-// An external test package may depend upon members of the augmented
-// package that are not in the unaugmented package, such as functions
-// that expose internals.  (See bufio/export_test.go for an example.)
-// So, the loader must ensure that for each external test package
-// it loads, it also augments the corresponding non-test package.
-//
-// The import graph over n unaugmented packages must be acyclic; the
-// import graph over n-1 unaugmented packages plus one augmented
-// package must also be acyclic.  ('go test' relies on this.)  But the
-// import graph over n augmented packages may contain cycles.
-//
-// First, all the (unaugmented) non-test packages and their
-// dependencies are imported in the usual way; the loader reports an
-// error if it detects an import cycle.
-//
-// Then, each package P for which testing is desired is augmented by
-// the list P' of its in-package test files, by calling
-// (*types.Checker).Files.  This arrangement ensures that P' may
-// reference definitions within P, but P may not reference definitions
-// within P'.  Furthermore, P' may import any other package, including
-// ones that depend upon P, without an import cycle error.
-//
-// Consider two packages A and B, both of which have lists of
-// in-package test files we'll call A' and B', and which have the
-// following import graph edges:
-//    B  imports A
-//    B' imports A
-//    A' imports B
-// This last edge would be expected to create an error were it not
-// for the special type-checking discipline above.
-// Cycles of size greater than two are possible.  For example:
-//   compress/bzip2/bzip2_test.go (package bzip2)  imports "io/ioutil"
-//   io/ioutil/tempfile_test.go   (package ioutil) imports "regexp"
-//   regexp/exec_test.go          (package regexp) imports "compress/bzip2"
-//
-//
-// Concurrency
-// -----------
-//
-// Let us define the import dependency graph as follows.  Each node is a
-// list of files passed to (Checker).Files at once.  Many of these lists
-// are the production code of an importable Go package, so those nodes
-// are labelled by the package's path.  The remaining nodes are
-// ad hoc packages and lists of in-package *_test.go files that augment
-// an importable package; those nodes have no label.
-//
-// The edges of the graph represent import statements appearing within a
-// file.  An edge connects a node (a list of files) to the node it
-// imports, which is importable and thus always labelled.
-//
-// Loading is controlled by this dependency graph.
-//
-// To reduce I/O latency, we start loading a package's dependencies
-// asynchronously as soon as we've parsed its files and enumerated its
-// imports (scanImports).  This performs a preorder traversal of the
-// import dependency graph.
-//
-// To exploit hardware parallelism, we type-check unrelated packages in
-// parallel, where "unrelated" means not ordered by the partial order of
-// the import dependency graph.
-//
-// We use a concurrency-safe non-blocking cache (importer.imported) to
-// record the results of type-checking, whether success or failure.  An
-// entry is created in this cache by startLoad the first time the
-// package is imported.  The first goroutine to request an entry becomes
-// responsible for completing the task and broadcasting completion to
-// subsequent requestors, which block until then.
-//
-// Type checking occurs in (parallel) postorder: we cannot type-check a
-// set of files until we have loaded and type-checked all of their
-// immediate dependencies (and thus all of their transitive
-// dependencies). If the input were guaranteed free of import cycles,
-// this would be trivial: we could simply wait for completion of the
-// dependencies and then invoke the typechecker.
-//
-// But as we saw in the 'go test' section above, some cycles in the
-// import graph over packages are actually legal, so long as the
-// cycle-forming edge originates in the in-package test files that
-// augment the package.  This explains why the nodes of the import
-// dependency graph are not packages, but lists of files: the unlabelled
-// nodes avoid the cycles.  Consider packages A and B where B imports A
-// and A's in-package tests AT import B.  The naively constructed import
-// graph over packages would contain a cycle (A+AT) --> B --> (A+AT) but
-// the graph over lists of files is AT --> B --> A, where AT is an
-// unlabelled node.
-//
-// Awaiting completion of the dependencies in a cyclic graph would
-// deadlock, so we must materialize the import dependency graph (as
-// importer.graph) and check whether each import edge forms a cycle.  If
-// x imports y, and the graph already contains a path from y to x, then
-// there is an import cycle, in which case the processing of x must not
-// wait for the completion of processing of y.
-//
-// When the type-checker makes a callback (doImport) to the loader for a
-// given import edge, there are two possible cases.  In the normal case,
-// the dependency has already been completely type-checked; doImport
-// does a cache lookup and returns it.  In the cyclic case, the entry in
-// the cache is still necessarily incomplete, indicating a cycle.  We
-// perform the cycle check again to obtain the error message, and return
-// the error.
-//
-// The result of using concurrency is about a 2.5x speedup for stdlib_test.
-
-// TODO(adonovan): overhaul the package documentation.

-const Usage = `gorename: precise type-safe renaming of identifiers in Go source code.
-
-Usage:
-
- gorename (-from <spec> | -offset <file>:#<byte-offset>) -to <name> [-force]
-
-You must specify the object (named entity) to rename using the -offset
-or -from flag.  Exactly one must be specified.
-
-Flags:
-
--offset    specifies the filename and byte offset of an identifier to rename.
-           This form is intended for use by text editors.
-
--from      specifies the object to rename using a query notation;
-           This form is intended for interactive use at the command line.
-           A legal -from query has one of the following forms:
-
-  "encoding/json".Decoder.Decode        method of package-level named type
-  (*"encoding/json".Decoder).Decode     ditto, alternative syntax
-  "encoding/json".Decoder.buf           field of package-level named struct type
-  "encoding/json".HTMLEscape            package member (const, func, var, type)
-  "encoding/json".Decoder.Decode::x     local object x within a method
-  "encoding/json".HTMLEscape::x         local object x within a function
-  "encoding/json"::x                    object x anywhere within a package
-  json.go::x                            object x within file json.go
-
-           Double-quotes must be escaped when writing a shell command.
-           Quotes may be omitted for single-segment import paths such as "fmt".
-
-           For methods, the parens and '*' on the receiver type are both
-           optional.
-
-           It is an error if one of the ::x queries matches multiple
-           objects.
-
--to        the new name.
-
--force     causes the renaming to proceed even if conflicts were reported.
-           The resulting program may be ill-formed, or experience a change
-           in behaviour.
-
-           WARNING: this flag may even cause the renaming tool to crash.
-           (In due course this bug will be fixed by moving certain
-           analyses into the type-checker.)
-
--d         display diffs instead of rewriting files
-
--v         enables verbose logging.
-
-gorename automatically computes the set of packages that might be
-affected.  For a local renaming, this is just the package specified by
--from or -offset, but for a potentially exported name, gorename scans
-the workspace ($GOROOT and $GOPATH).
-
-gorename rejects renamings of concrete methods that would change the
-assignability relation between types and interfaces.  If the interface
-change was intentional, initiate the renaming at the interface method.
-
-gorename rejects any renaming that would create a conflict at the point
-of declaration, or a reference conflict (ambiguity or shadowing), or
-anything else that could cause the resulting program not to compile.
-
-
-Examples:
-
-$ gorename -offset file.go:#123 -to foo
-
-  Rename the object whose identifier is at byte offset 123 within file file.go.
-
-$ gorename -from '"bytes".Buffer.Len' -to Size
-
-  Rename the "Len" method of the *bytes.Buffer type to "Size".
-
----- TODO ----
-
-Correctness:
-- handle dot imports correctly
-- document limitations (reflection, 'implements' algorithm).
-- sketch a proof of exhaustiveness.
-
-Features:
-- support running on packages specified as *.go files on the command line
-- support running on programs containing errors (loader.Config.AllowErrors)
-- allow users to specify a scope other than "global" (to avoid being
-  stuck by neglected packages in $GOPATH that don't build).
-- support renaming the package clause (no object)
-- support renaming an import path (no ident or object)
-  (requires filesystem + SCM updates).
-- detect and reject edits to autogenerated files (cgo, protobufs)
-  and optionally $GOROOT packages.
-- report all conflicts, or at least all qualitatively distinct ones.
-  Sometimes we stop to avoid redundancy, but
-  it may give a disproportionate sense of safety in -force mode.
-- support renaming all instances of a pattern, e.g.
-  all receiver vars of a given type,
-  all local variables of a given type,
-  all PkgNames for a given package.
-- emit JSON output for other editors and tools.

-# Go App Engine packages
-
-[![Build Status](https://travis-ci.org/golang/appengine.svg)](https://travis-ci.org/golang/appengine)
-
-This repository supports the Go runtime on App Engine,
-including both the standard App Engine and the
-"App Engine flexible environment" (formerly known as "Managed VMs").
-It provides APIs for interacting with App Engine services.
-Its canonical import path is `google.golang.org/appengine`.
-
-See https://cloud.google.com/appengine/docs/go/
-for more information.
-
-File issue reports and feature requests on the [Google App Engine issue
-tracker](https://code.google.com/p/googleappengine/issues/entry?template=Go%20defect).
-
-## Directory structure
-The top level directory of this repository is the `appengine` package. It
-contains the
-basic APIs (e.g. `appengine.NewContext`) that apply across APIs. Specific API
-packages are in subdirectories (e.g. `datastore`).
-
-There is an `internal` subdirectory that contains service protocol buffers,
-plus packages required for connectivity to make API calls. App Engine apps
-should not directly import any package under `internal`.
-
-## Updating a Go App Engine app
-
-This section describes how to update an older Go App Engine app to use
-these packages. A provided tool, `aefix`, can help automate steps 2 and 3
-(run `go get google.golang.org/appengine/cmd/aefix` to install it), but
-read the details below since `aefix` can't perform all the changes.
-
-### 1. Update YAML files (App Engine flexible environment / Managed VMs only)
-
-The `app.yaml` file (and YAML files for modules) should have these new lines added:
-```
-vm: true
-```
-See https://cloud.google.com/appengine/docs/go/modules/#Go_Instance_scaling_and_class for details.
-
-### 2. Update import paths
-
-The import paths for App Engine packages are now fully qualified, based at `google.golang.org/appengine`.
-You will need to update your code to use import paths starting with that; for instance,
-code importing `appengine/datastore` will now need to import `google.golang.org/appengine/datastore`.
-
-### 3. Update code using deprecated, removed or modified APIs
-
-Most App Engine services are available with exactly the same API.
-A few APIs were cleaned up, and some are not available yet.
-This list summarises the differences:
-
-* `appengine.Context` has been replaced with the `Context` type from `golang.org/x/net/context`.
-* Logging methods that were on `appengine.Context` are now functions in `google.golang.org/appengine/log`.
-* `appengine.Timeout` has been removed. Use `context.WithTimeout` instead.
-* `appengine.Datacenter` now takes a `context.Context` argument.
-* `datastore.PropertyLoadSaver` has been simplified to use slices in place of channels.
-* `delay.Call` now returns an error.
-* `search.FieldLoadSaver` now handles document metadata.
-* `urlfetch.Transport` no longer has a Deadline field; set a deadline on the
-  `context.Context` instead.
-* `aetest` no longer declares its own Context type, and uses the standard one instead.
-* `taskqueue.QueueStats` no longer takes a maxTasks argument. That argument has been
-  deprecated and unused for a long time.
-* `appengine.BackendHostname` and `appengine.BackendInstance` were for the deprecated backends feature.
-  Use `appengine.ModuleHostname`and `appengine.ModuleName` instead.
-* Most of `appengine/file` and parts of `appengine/blobstore` are deprecated.
-  Use [Google Cloud Storage](https://godoc.org/cloud.google.com/go/storage) if the
-  feature you require is not present in the new
-  [blobstore package](https://google.golang.org/appengine/blobstore).
-* `appengine/socket` is not required on App Engine flexible environment / Managed VMs.
-  Use the standard `net` package instead.

-Package datastore provides a client for App Engine's datastore service.
-
-
-Basic Operations
-
-Entities are the unit of storage and are associated with a key. A key
-consists of an optional parent key, a string application ID, a string kind
-(also known as an entity type), and either a StringID or an IntID. A
-StringID is also known as an entity name or key name.
-
-It is valid to create a key with a zero StringID and a zero IntID; this is
-called an incomplete key, and does not refer to any saved entity. Putting an
-entity into the datastore under an incomplete key will cause a unique key
-to be generated for that entity, with a non-zero IntID.
-
-An entity's contents are a mapping from case-sensitive field names to values.
-Valid value types are:
-  - signed integers (int, int8, int16, int32 and int64),
-  - bool,
-  - string,
-  - float32 and float64,
-  - []byte (up to 1 megabyte in length),
-  - any type whose underlying type is one of the above predeclared types,
-  - ByteString,
-  - *Key,
-  - time.Time (stored with microsecond precision),
-  - appengine.BlobKey,
-  - appengine.GeoPoint,
-  - structs whose fields are all valid value types,
-  - slices of any of the above.
-
-Slices of structs are valid, as are structs that contain slices. However, if
-one struct contains another, then at most one of those can be repeated. This
-disqualifies recursively defined struct types: any struct T that (directly or
-indirectly) contains a []T.
-
-The Get and Put functions load and save an entity's contents. An entity's
-contents are typically represented by a struct pointer.
-
-Example code:
-
-	type Entity struct {
-		Value string
-	}
-
-	func handle(w http.ResponseWriter, r *http.Request) {
-		ctx := appengine.NewContext(r)
-
-		k := datastore.NewKey(ctx, "Entity", "stringID", 0, nil)
-		e := new(Entity)
-		if err := datastore.Get(ctx, k, e); err != nil {
-			http.Error(w, err.Error(), 500)
-			return
-		}
-
-		old := e.Value
-		e.Value = r.URL.Path
-
-		if _, err := datastore.Put(ctx, k, e); err != nil {
-			http.Error(w, err.Error(), 500)
-			return
-		}
-
-		w.Header().Set("Content-Type", "text/plain; charset=utf-8")
-		fmt.Fprintf(w, "old=%q\nnew=%q\n", old, e.Value)
-	}
-
-GetMulti, PutMulti and DeleteMulti are batch versions of the Get, Put and
-Delete functions. They take a []*Key instead of a *Key, and may return an
-appengine.MultiError when encountering partial failure.
-
-
-Properties
-
-An entity's contents can be represented by a variety of types. These are
-typically struct pointers, but can also be any type that implements the
-PropertyLoadSaver interface. If using a struct pointer, you do not have to
-explicitly implement the PropertyLoadSaver interface; the datastore will
-automatically convert via reflection. If a struct pointer does implement that
-interface then those methods will be used in preference to the default
-behavior for struct pointers. Struct pointers are more strongly typed and are
-easier to use; PropertyLoadSavers are more flexible.
-
-The actual types passed do not have to match between Get and Put calls or even
-across different App Engine requests. It is valid to put a *PropertyList and
-get that same entity as a *myStruct, or put a *myStruct0 and get a *myStruct1.
-Conceptually, any entity is saved as a sequence of properties, and is loaded
-into the destination value on a property-by-property basis. When loading into
-a struct pointer, an entity that cannot be completely represented (such as a
-missing field) will result in an ErrFieldMismatch error but it is up to the
-caller whether this error is fatal, recoverable or ignorable.
-
-By default, for struct pointers, all properties are potentially indexed, and
-the property name is the same as the field name (and hence must start with an
-upper case letter). Fields may have a `datastore:"name,options"` tag. The tag
-name is the property name, which must be one or more valid Go identifiers
-joined by ".", but may start with a lower case letter. An empty tag name means
-to just use the field name. A "-" tag name means that the datastore will
-ignore that field. If options is "noindex" then the field will not be indexed.
-If the options is "" then the comma may be omitted. There are no other
-recognized options.
-
-Fields (except for []byte) are indexed by default. Strings longer than 1500
-bytes cannot be indexed; fields used to store long strings should be
-tagged with "noindex". Similarly, ByteStrings longer than 1500 bytes cannot be
-indexed.
-
-Example code:
-
-	// A and B are renamed to a and b.
-	// A, C and J are not indexed.
-	// D's tag is equivalent to having no tag at all (E).
-	// I is ignored entirely by the datastore.
-	// J has tag information for both the datastore and json packages.
-	type TaggedStruct struct {
-		A int `datastore:"a,noindex"`
-		B int `datastore:"b"`
-		C int `datastore:",noindex"`
-		D int `datastore:""`
-		E int
-		I int `datastore:"-"`
-		J int `datastore:",noindex" json:"j"`
-	}
-
-
-Structured Properties
-
-If the struct pointed to contains other structs, then the nested or embedded
-structs are flattened. For example, given these definitions:
-
-	type Inner1 struct {
-		W int32
-		X string
-	}
-
-	type Inner2 struct {
-		Y float64
-	}
-
-	type Inner3 struct {
-		Z bool
-	}
-
-	type Outer struct {
-		A int16
-		I []Inner1
-		J Inner2
-		Inner3
-	}
-
-then an Outer's properties would be equivalent to those of:
-
-	type OuterEquivalent struct {
-		A     int16
-		IDotW []int32  `datastore:"I.W"`
-		IDotX []string `datastore:"I.X"`
-		JDotY float64  `datastore:"J.Y"`
-		Z     bool
-	}
-
-If Outer's embedded Inner3 field was tagged as `datastore:"Foo"` then the
-equivalent field would instead be: FooDotZ bool `datastore:"Foo.Z"`.
-
-If an outer struct is tagged "noindex" then all of its implicit flattened
-fields are effectively "noindex".
-
-
-The PropertyLoadSaver Interface
-
-An entity's contents can also be represented by any type that implements the
-PropertyLoadSaver interface. This type may be a struct pointer, but it does
-not have to be. The datastore package will call Load when getting the entity's
-contents, and Save when putting the entity's contents.
-Possible uses include deriving non-stored fields, verifying fields, or indexing
-a field only if its value is positive.
-
-Example code:
-
-	type CustomPropsExample struct {
-		I, J int
-		// Sum is not stored, but should always be equal to I + J.
-		Sum int `datastore:"-"`
-	}
-
-	func (x *CustomPropsExample) Load(ps []datastore.Property) error {
-		// Load I and J as usual.
-		if err := datastore.LoadStruct(x, ps); err != nil {
-			return err
-		}
-		// Derive the Sum field.
-		x.Sum = x.I + x.J
-		return nil
-	}
-
-	func (x *CustomPropsExample) Save() ([]datastore.Property, error) {
-		// Validate the Sum field.
-		if x.Sum != x.I + x.J {
-			return errors.New("CustomPropsExample has inconsistent sum")
-		}
-		// Save I and J as usual. The code below is equivalent to calling
-		// "return datastore.SaveStruct(x)", but is done manually for
-		// demonstration purposes.
-		return []datastore.Property{
-			{
-				Name:  "I",
-				Value: int64(x.I),
-			},
-			{
-				Name:  "J",
-				Value: int64(x.J),
-			},
-		}
-	}
-
-The *PropertyList type implements PropertyLoadSaver, and can therefore hold an
-arbitrary entity's contents.
-
-
-Queries
-
-Queries retrieve entities based on their properties or key's ancestry. Running
-a query yields an iterator of results: either keys or (key, entity) pairs.
-Queries are re-usable and it is safe to call Query.Run from concurrent
-goroutines. Iterators are not safe for concurrent use.
-
-Queries are immutable, and are either created by calling NewQuery, or derived
-from an existing query by calling a method like Filter or Order that returns a
-new query value. A query is typically constructed by calling NewQuery followed
-by a chain of zero or more such methods. These methods are:
-  - Ancestor and Filter constrain the entities returned by running a query.
-  - Order affects the order in which they are returned.
-  - Project constrains the fields returned.
-  - Distinct de-duplicates projected entities.
-  - KeysOnly makes the iterator return only keys, not (key, entity) pairs.
-  - Start, End, Offset and Limit define which sub-sequence of matching entities
-    to return. Start and End take cursors, Offset and Limit take integers. Start
-    and Offset affect the first result, End and Limit affect the last result.
-    If both Start and Offset are set, then the offset is relative to Start.
-    If both End and Limit are set, then the earliest constraint wins. Limit is
-    relative to Start+Offset, not relative to End. As a special case, a
-    negative limit means unlimited.
-
-Example code:
-
-	type Widget struct {
-		Description string
-		Price       int
-	}
-
-	func handle(w http.ResponseWriter, r *http.Request) {
-		ctx := appengine.NewContext(r)
-		q := datastore.NewQuery("Widget").
-			Filter("Price <", 1000).
-			Order("-Price")
-		b := new(bytes.Buffer)
-		for t := q.Run(ctx); ; {
-			var x Widget
-			key, err := t.Next(&x)
-			if err == datastore.Done {
-				break
-			}
-			if err != nil {
-				serveError(ctx, w, err)
-				return
-			}
-			fmt.Fprintf(b, "Key=%v\nWidget=%#v\n\n", key, x)
-		}
-		w.Header().Set("Content-Type", "text/plain; charset=utf-8")
-		io.Copy(w, b)
-	}
-
-
-Transactions
-
-RunInTransaction runs a function in a transaction.
-
-Example code:
-
-	type Counter struct {
-		Count int
-	}
-
-	func inc(ctx context.Context, key *datastore.Key) (int, error) {
-		var x Counter
-		if err := datastore.Get(ctx, key, &x); err != nil && err != datastore.ErrNoSuchEntity {
-			return 0, err
-		}
-		x.Count++
-		if _, err := datastore.Put(ctx, key, &x); err != nil {
-			return 0, err
-		}
-		return x.Count, nil
-	}
-
-	func handle(w http.ResponseWriter, r *http.Request) {

-Metadata
-
-The datastore package provides access to some of App Engine's datastore
-metadata. This metadata includes information about the entity groups,
-namespaces, entity kinds, and properties in the datastore, as well as the
-property representations for each property.
-
-Example code:
-
-	func handle(w http.ResponseWriter, r *http.Request) {
-		// Print all the kinds in the datastore, with all the indexed
-		// properties (and their representations) for each.
-		ctx := appengine.NewContext(r)
-
-		kinds, err := datastore.Kinds(ctx)
-		if err != nil {
-			serveError(ctx, w, err)
-			return
-		}
-
-		w.Header().Set("Content-Type", "text/plain; charset=utf-8")
-		for _, kind := range kinds {
-			fmt.Fprintf(w, "%s:\n", kind)
-			props, err := datastore.KindProperties(ctx, kind)
-			if err != nil {
-				fmt.Fprintln(w, "\t(unable to retrieve properties)")
-				continue
-			}
-			for p, rep := range props {
-				fmt.Fprintf(w, "\t-%s (%s)\n", p, strings.Join(", ", rep))
-			}
