In a Pull Request touching 80 files, polyproto-rs (polyproto reference implementation in Rust) was painfully rid of all lintable bad style, missing documentation, inconsistent usages of things and sneaky ways to enabling crate features which would break the build of the library
All of this was enabled by refactored CI and style-checking suites now powered by nix and @lix_project (,,that's their logo right,?)
