internal/impl: faster oneof marshaling Change size, marshal, and isinit operations on oneofs to look up the currently-set oneof type in a map rather than testing for each possible oneof field in turn. Significantly improves oneof encoding speed for oneofs with a substantial number of fields: go test ./proto -bench=./oneof.*string.*test.TestAll -benchmem -count=8 -cpu=1 name old time/op new time/op delta Encode/oneof_(string)_(*test.TestAllTypes) 911ns ± 1% 397ns ± 3% -56.45% (p=0.000 n=8+7) Decode/oneof_(string)_(*test.TestAllTypes) 899ns ± 1% 922ns ± 1% +2.49% (p=0.001 n=7+7) Fixes golang/protobuf#950 Change-Id: I9393a87975ce09011d885a8af4a63a639ea8452f Reviewed-on: https://go-review.googlesource.com/c/protobuf/+/210281 Reviewed-by: Joe Tsai <thebrokentoaster@gmail.com>
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.

We appreciate community contributions. See CONTRIBUTING.md.
