## Project history and usage

cargo-udeps is a Cargo subcommand for finding unused dependencies declared in Cargo.toml.

### Project history

The official README says cargo-udeps finds unused dependencies in Cargo.toml and needs Rust nightly to run, while compiling on stable.

### Adoption history

GitHub records the repository as created in August 2019, and crates.io records the first release shortly after. The README lists Nix/NixOS, Arch Linux, and Homebrew packages; the input package facts also list Alpine.

### How it is used

The README documents `cargo +nightly udeps`, package and workspace Cargo.toml metadata for ignore lists, and pre-commit hook usage.

### Why package nerds care

cargo-udeps is useful to maintainers because unused dependencies affect build time, dependency graphs, packaging policy, and audit surface; its README trophy case records real projects where unused dependencies were removed.

### Timeline

- 2019: GitHub repository created and first crates.io release recorded.
- 2026: crates.io records max_version 0.1.61.

### Related projects

- The README links deps.rs status and lists downstream projects where cargo-udeps found unused dependencies.
