Lint uses of to/from_ne_bytes #10765
Comments
I'm thinking there should also be a lint for big endian and little endian functions. They'd both be allowed by default, but if for instance, I'm writing a serialization thing and it always uses little endian (never big endian or native endian), it'd be nice to have a lint that stops me from accidentally using big endian or native endian. |
I was looking into this lint before and wanted to add exactly this. I got @rustbot claim |
Fixed errors and lack of documentation in mod.rs. Added type check and test case for string slice. Added supposed check for windows paths. Build failure fix. Build fix attempt rust-lang#2. Fixed formatting. Refactor unwind from Option to a new enum Fix tools Make elaborator generic Merge commit '83e42a2337dadac915c956d125f1d69132f36425' into clippyup Tweak output for 'add line' suggestion Special-case item attributes in the suggestion output resolve: Pre-compute non-reexport module children Instead of repeating the same logic by walking HIR during metadata encoding. The only difference is that we are no longer encoding `macro_rules` items, but we never currently need them as a part of this list. They can be encoded separately if this need ever arises. `module_reexports` is also un-querified, because I don't see any reasons to make it a query, only overhead. Alloc `hir::Lit` in an arena to remove the destructor from `Expr` This allows allocating `Expr`s into a dropless arena, which is useful for using length prefixed thing slices in HIR, since these can only be allocated in the dropless arena and not in a typed arena. This is something I'm working on. clippy: add test for rust-lang#10645 Remove very useless `as_substs` usage from clippy Force -Zflatten-format-args=no in Clippy. Remove WithOptconstParam. offset_of Evaluate place expression in `PlaceMention`. Allow `LocalDefId` as the argument to `def_path_str` Merge commit 'a3ed905928a03b6e433d0b429190bf3a847128b3' into clippyup Clippy book: hotfix for broken link change usages of explicit_item_bounds to bound_explicit_item_bounds add EarlyBinder to output of explicit_item_bounds; replace bound_explicit_item_bounds usages; remove bound_explicit_item_bounds query add subst_identity_iter and subst_identity_iter_copied methods on EarlyBinder; use this to simplify some EarlyBinder noise around explicit_item_bounds calls rename `needs_infer` to `has_infer` Make clippy happy uplift `clippy::clone_double_ref` as `suspicious_double_ref_op` clean up Colon from clippy Restrict `From<S>` for `{D,Subd}iagnosticMessage`. Currently a `{D,Subd}iagnosticMessage` can be created from any type that impls `Into<String>`. That includes `&str`, `String`, and `Cow<'static, str>`, which are reasonable. It also includes `&String`, which is pretty weird, and results in many places making unnecessary allocations for patterns like this: ``` self.fatal(&format!(...)) ``` This creates a string with `format!`, takes a reference, passes the reference to `fatal`, which does an `into()`, which clones the reference, doing a second allocation. Two allocations for a single string, bleh. This commit changes the `From` impls so that you can only create a `{D,Subd}iagnosticMessage` from `&str`, `String`, or `Cow<'static, str>`. This requires changing all the places that currently create one from a `&String`. Most of these are of the `&format!(...)` form described above; each one removes an unnecessary static `&`, plus an allocation when executed. There are also a few places where the existing use of `&String` was more reasonable; these now just use `clone()` at the call site. As well as making the code nicer and more efficient, this is a step towards possibly using `Cow<'static, str>` in `{D,Subd}iagnosticMessage::{Str,Eager}`. That would require changing the `From<&'a str>` impls to `From<&'static str>`, which is doable, but I'm not yet sure if it's worthwhile.

Exclude inherent projections from some alias ty matches Merge commit '435a8ad86c7a33bd7ffb91c59039943408d3b6aa' into clippyup Rename `drop_copy` lint to `dropping_copy_types` Rename `forget_copy` lint to `forgetting_copy_types` Rename `drop_ref` lint to `dropping_references` Rename `forget_ref` lint to `forgetting_references` Replace EarlyBinder(x) with EarlyBinder::new(x) Make EarlyBinder's inner value private; and fix all of the resulting errors Use `Cow` in `{D,Subd}iagnosticMessage`. Each of `{D,Subd}iagnosticMessage::{Str,Eager}` has a comment: ``` // FIXME(davidtwco): can a `Cow<'static, str>` be used here? ``` This commit answers that question in the affirmative. It's not the most compelling change ever, but it might be worth merging. This requires changing the `impl<'a> From<&'a str>` impls to `impl From<&'static str>`, which involves a bunch of knock-on changes that require/result in call sites being a little more precise about exactly what kind of string they use to create errors, and not just `&str`. This will result in fewer unnecessary allocations, though this will not have any notable perf effects given that these are error paths. Note that I was lazy within Clippy, using `to_string` in a few places to preserve the existing string imprecision. I could have used `impl Into<{D,Subd}iagnosticMessage>` in various places as is done in the compiler, but that would have required changes to *many* call sites (mostly changing `&format("...")` to `format!("...")`) which didn't seem worthwhile.

Make it clear there these are only coercion to make it clear why only some pointer related "casts" are in the enum. Delete `to_string_in_format_args_incremental.rs` It fails CI and passes locally.

Each of `{D,Subd}iagnosticMessage::{Str,Eager}` has a comment: ``` // FIXME(davidtwco): can a `Cow<'static, str>` be used here? ``` This commit answers that question in the affirmative. It's not the most compelling change ever, but it might be worth merging. This requires changing the `impl<'a> From<&'a str>` impls to `impl From<&'static str>`, which involves a bunch of knock-on changes that require/result in call sites being a little more precise about exactly what kind of string they use to create errors, and not just `&str`. This will result in fewer unnecessary allocations, though this will not have any notable perf effects given that these are error paths. Note that I was lazy within Clippy, using `to_string` in a few places to preserve the existing string imprecision. I could have used `impl Into<{D,Subd}iagnosticMessage>` in various places as is done in the compiler, but that would have required changes to *many* call sites (mostly changing `&format("...")` to `format!("...")`) which didn't seem worthwhile.

Each of `{D,Subd}iagnosticMessage::{Str,Eager}` has a comment: ``` // FIXME(davidtwco): can a `Cow<'static, str>` be used here? ``` This commit answers that question in the affirmative. It's not the most compelling change ever, but it might be worth merging. This requires changing the `impl<'a> From<&'a str>` impls to `impl From<&'static str>`, which involves a bunch of knock-on changes that require/result in call sites being a little more precise about exactly what kind of string they use to create errors, and not just `&str`. This will result in fewer unnecessary allocations, though this will not have any notable perf effects given that these are error paths. Note that I was lazy within Clippy, using `to_string` in a few places to preserve the existing string imprecision. I could have used `impl Into<{D,Subd}iagnosticMessage>` in various places as is done in the compiler, but that would have required changes to *many* call sites (mostly changing `&format("...")` to `format!("...")`) which didn't seem worthwhile.

Handle back/forward when using URL parameters for filter states Clippy Lints page - Delay updating of the URL in response to search input Update on blur, enter keypress, and a debounced delay of 1000 ms. This keeps the URL updated, but not distractingly so. Clippy Lints page - Do not show groups in URL parameters if reset to defaults Clippy Lints page - Fix path watch triggering Clippy Lints page - Do not show filters in URL if configured as default values only lint when `cast_from` and `cast_to`'s ty are the same weird manual_let_else: only add () around PatKind::Or at the top level At the top level, () are required, but on the levels below they are not.

What it does
Lint uses of
from_ne_bytes
andto_ne_bytes
for code that needs to be endian aware. It may be desirable to force a developer to consider the endian which data should be stored in, especially when sending data across a network or to another machine.Lint Name
endian_bytes
Category
restriction
Advantage
Drawbacks
Sometimes it may be desirable to use the host endianness. For example a protocol like Wayland uses host endian.
