buffa is a zero-copy Rust Protobuf implementation with editions support (2023/2024), no_std compatibility, and view types for borrowed field access. Passes the protobuf conformance suite (5539 binary+JSON tests). The plugin emits one .rs file per proto file using a flat naming convention (`foo/v1/bar.proto` -> `foo.v1.bar.rs`), matching what BSR expects. Module tree assembly is a separate `protoc-gen-buffa-packaging` plugin in the same repo, not needed for BSR (which synthesizes lib.rs server-side).

I think we might want to make a top-level anthropics org for this, instead of under community - also re: connect-rust. |

Adds the
protoc-gen-buffaplugin for Rust protobuf code generation.About buffa
buffa is a zero-copy Rust Protobuf implementation with:
&str/&[u8]field access without owned allocationCrates are on crates.io:
buffa,buffa-types,protoc-gen-buffa.Output convention
The plugin emits one
.rsfile per proto file with a flat naming scheme:foo/v1/bar.proto->foo.v1.bar.rs. No subdirectories, no mod.rs - module tree assembly is a separate local-only packaging plugin (protoc-gen-buffa-packaging) that BSR does not need since it synthesizes lib.rs server-side.Open questions for review
community/anthropics-buffafollowing theneoeinstein-prostpattern. Happy to move if there is a preferred location.json=trueandviews=true. If BSR has conventions for which opts to expose vs bake in, please advise.pkg.subpkg.file.rs) is flat but per-proto-file, not per-package like prost. If BSR's lib.rs synthesis expects per-package naming instead, we can add a plugin option to switch modes.Process note
CONTRIBUTING.md asks for an issue first - happy to open one if you would prefer to discuss before reviewing the PR. Filed this as a draft in the meantime.
Related: #2334 (connectrpc/rust) declares this plugin as a dep, so this one would need to land first.
