Stash fast-path information for extensions on the ExtensionInfo. In the usual case where an ExtensionType's underlying implementation is an *ExtensionInfo, fetching the fast-path information becomes a type assertion rather than a mutex-guarded map access. Maintain a global sync.Map for the case where an ExtensionType isn't an *ExtensionInfo. Substantially improves performance for fast-path operations on extensions: Encode/MessageSet_type_id_before_message_content-12 267ns ± 1% 185ns ± 1% -30.44% (p=0.001 n=7+7) Encode/basic_scalar_types_(*test.TestAllExtensions)-12 1.94µs ± 1% 0.40µs ± 1% -79.32% (p=0.000 n=8+7) Change-Id: If048b521deb3665a090ea3d0a178c61691d4201e Reviewed-on: https://go-review.googlesource.com/c/protobuf/+/210540 Reviewed-by: Joe Tsai <joetsai@google.com>
Next Generation Go Protocol Buffers
WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.
This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
