During June 2025, Purkhusid developed custom crate name support for Prost-generated crates in the bazelbuild/rules_rust repository. By enabling explicit crate naming within the build system, this work addressed conflicts that arise when multiple generated crates share similar base names in proto-driven Rust projects. The implementation leveraged Starlark and Bazel, integrating with Protocol Buffers to allow users to define crate names directly in rust_prost_transform. This approach improved build reliability and scalability for multi-crate environments, providing greater user control over Rust target naming. The work demonstrated a focused application of build system expertise and contributed to more maintainable Rust codebases.
