TL;DR
To safeguard the Rust standard library from unintentional changes, the Rust community implemented cargo-semver-checks, a tool designed to enforce semantic versioning. This initiative involved extensive collaboration, resulting in over 15,000 lines of code and numerous pull requests.
✦ Why It Matters
Implement cargo-semver-checks in your own projects to prevent accidental breakage.
Key Takeaways
How It Works
cargo-semver-checks analyzes the stability of APIs in the Rust standard library by reading stability attributes from rustdoc JSON. It distinguishes between stable and unstable features, ensuring that changes to stable APIs are flagged to prevent accidental breakage.
This process allows developers to maintain a clear understanding of which parts of their code are safe to use in stable releases.
