About rust-library-performance-features
A skill for measuring and shipping performance improvements in Rust libraries, with optional capabilities separated by Cargo features. It guides library maintainers through benchmarking, feature-matrix testing, and documenting performance claims.
Key features
- 01Define representative operations and input sizes
- 02Benchmark before and after optimization
- 03Compare implementations with one harness
- 04Gate optional capabilities with Cargo features
- 05Test feature combinations, including no defaults
- 06Document measurement scope and commands
Use cases
- 01Optimize a library hot path
- 02Add benchmarks for downstream operations
- 03Review optional dependencies and Cargo features
- 04Validate performance claims before release

From the project READMERust Library Performance Features
Use this skill when a Rust library needs performance work that can be measured and shipped behind clear Cargo feature boundaries.
Core Workflow
- Define the library operation and input sizes that matter to downstream users.
- Add or repair benchmarks before optimizing.
- Compare baseline and candidate implementations with the same harness.
- Use Cargo features for optional capabilities and dependencies.
- Test the feature matrix, including default features disabled.
- Document performance claims with scope and measurement commands.
