During March 2026, Idy contributed to the bazelbuild/rules_rust repository by delivering Mac Catalyst platform support, introducing new platform triples for aarch64-apple-ios-macabi and x86_64-apple-ios-macabi. They mapped these triples to Catalyst-specific constraints within the triple_to_constraint_set logic, ensuring compatibility with crate_universe and improving cross-platform support for macOS consumers. Idy implemented comprehensive unit tests to validate both the parsing and mapping of these new triples, and addressed missing platform labels that previously caused breakages in crate_universe-generated selects. Their work demonstrated depth in Bazel and Rust, with a focus on robust unit testing and maintainable cross-platform build configurations.
