Support for Any.pack

[long1eu]

Hi!

Tha google.protobuf.Any type has a pack and unpack method. If is possible to added them? These are the js definitions.

/**
 * Packs the given message instance into this Any.
 * For binary format usage only.
 * @param {!Uint8Array} serialized The serialized data to pack.
 * @param {string} name The type name of this message object.
 * @param {string=} opt_typeUrlPrefix the type URL prefix.
 */
proto.google.protobuf.Any.prototype.pack = function(serialized, name,
                                                    opt_typeUrlPrefix) {
  if (!opt_typeUrlPrefix) {
    opt_typeUrlPrefix = 'type.googleapis.com/';
  }

  if (opt_typeUrlPrefix.substr(-1) != '/') {
    this.setTypeUrl(opt_typeUrlPrefix + '/' + name);
  } else {
    this.setTypeUrl(opt_typeUrlPrefix + name);
  }

  this.setValue(serialized);
};


/**
 * @template T
 * Unpacks this Any into the given message object.
 * @param {function(Uint8Array):T} deserialize Function that will deserialize
 *     the binary data properly.
 * @param {string} name The expected type name of this message object.
 * @return {?T} If the name matched the expected name, returns the deserialized
 *     object, otherwise returns null.
 */
proto.google.protobuf.Any.prototype.unpack = function(deserialize, name) {
  if (this.getTypeName() == name) {
    return deserialize(this.getValue_asU8());
  } else {
    return null;
  }
};

Hi @long1eu,

I have made some test.

1. git clone git@github.com:agreatfool/grpc_tools_node_protoc_ts.git
2. cd grpc_tools_node_protoc_ts/examples
3. add file examples/proto/goolge/protobuf/any.proto, source comes from here
   
4. edit book.proto file, add import "google/protobuf/any.proto"; and:
   
5. run examples/bash/build.sh, see what changed in file: examples/src/grpc/proto/book_pb.js

There is no pack & unpack generated.

And js codes generated come from grpc-tools. You'd better ask them about this.

Hey!

Thanks for this. As you can see the pack and unpack functions just combines the two already existing method. Good to know that this is not a ts issue. Thanks again.
