@UebelAndre maybe? Is this something that would be welcome in rules_rust to help avoid protoc compilation times for rust users?
I would happily review a PR adding this support :)

Hey! It'd definitely be welcome! 😄
Currently rules_rust requires the user to override the protoc compiler https://github.com/bazelbuild/rules_rust/blob/df7a6555de52d093183ba03694632fff400c106c/proto/protobuf/toolchain.bzl#L174 with a fixed label to replace it.
However Bazel 7 introduced
--incompatible_enable_proto_toolchain_resolution
and rules_proto 6.0 allows users to register a toolchain for protoc. Thetoolchain_type
is@rules_proto//proto:toolchain_type
: https://github.com/bazelbuild/rules_proto/blob/6.0.0-rc3/proto/BUILD#L57-L60https://registry.bazel.build/modules/toolchains_protoc is a reference implementation and has examples
Similar change in other language rules:
