Worked on the bazelbuild/rules_rust repository to enhance Rust documentation workflows within Bazel by introducing configurable documentation tooling. Developed a rustdoc_flags parameter for rust_doc_test, aligning its behavior with rust_doc and enabling custom flags during documentation tests. Added crate_features attribute support to both rust_doc() and rust_doc_test(), ensuring documentation generation and tests accurately reflect crate feature configurations. These improvements, implemented using Starlark and Python, increased reproducibility and consistency across documentation and testing processes. Focused on build system configuration and Rust integration, the work reduced discrepancies between documentation and code, streamlining developer experience and improving CI reliability for Rust projects using Bazel.
