protoc plugin for generating Rust code with buffa.

This binary follows the protoc plugin protocol:

1. Read a serialized CodeGeneratorRequest from stdin.
2. Pass the file descriptors to buffa-codegen.
3. Write a serialized CodeGeneratorResponse to stdout.

Usage: protoc --buffa_out=. --plugin=protoc-gen-buffa my_service.proto

Or with buf:

buf.gen.yaml

plugins: - local: protoc-gen-buffa out: src/gen
