history

Project history and usage

cargo-public-api is a Cargo subcommand and companion tooling for listing and diffing the public API of Rust library crates.

Project history

The GitHub repository was created in January 2022, and the crate appeared on crates.io in April 2022. The README explains that it builds rustdoc JSON and uses it to list public items or compare APIs across releases and commits.

Adoption history

The tool is packaged on crates.io and listed in Homebrew, Nix, and Arch package facts for this batch. crates.io classifies it as both a command-line utility and a Cargo plugin, reflecting its use from local terminals and CI.

How it is used

The README shows cargo public-api for listing a crate API, cargo public-api diff for comparing against a published version, latest release, or commit range, and a CI pattern that snapshots API output to catch unintended public API changes.

Why package nerds care

Rust package maintainers use it to make semver review concrete: instead of manually scanning exported items, they can diff rustdoc-derived public API output and gate changes in CI.

Timeline

2022: GitHub repository created and first crates.io release published.
2025: README compatibility matrix tied releases to specific rustdoc JSON nightly ranges.
2026: crates.io reported v0.52.0 as the latest release.

Related projects

The project relies on rustdoc JSON from the Rust toolchain.
The README recommends public-api, rustdoc-json, and rustup-toolchain crates for CI tests.
