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. ### Sources - - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
