We trust the compiler to optimize away the string->[]byte conversion in code like: b = wire.AppendBytes(b, []byte(s)) In testing (go 1.12.5 linux/amd64), this optimization is not happening. Perhaps newer versions of the compiler will optimize this, but we shouldn't rely on it; avoid unnecessary conversions.

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.
