hashgraph-online Rust 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.

Source Notes
Guidance is transformed and paraphrased from Herbert Wolverson, Advanced Hands-On Rust, especially Chapters 2 and 3 on creating, testing, optimizing, benchmarking, and feature-gating a library. Examples are original skeletons.
