## What it is
cargo-udeps is a Cargo subcommand that detects unused dependencies declared in a Rust project's Cargo.toml. It requires Rust nightly to run and can be used in CI or as a pre-commit hook.

## Use cases
- find unused dependencies in Cargo.toml
- detect unused crates in a Rust project
- clean up Cargo.toml dependencies
- check for unused dependencies in CI
- run dependency audit as a pre-commit hook
- ignore specific dependencies from unused checks

## When to choose
- you maintain a Rust project and want to remove dead dependencies
- you want automated unused-dependency checks in CI or pre-commit
- you work with Cargo workspaces and want workspace-wide checks

## When to avoid
- you cannot use Rust nightly toolchain
- you need fully accurate detection (some unused crates are missed, e.g. those used by std or shared with dependency graphs)
- you need per-version crate handling (crates are only handled per name)

## Facets
- artifact type: cli-tool
- maturity: active
- function: developer-tools, build-tool, dependency-audit, cli
- domain: developer-tools, version-control
- platform: windows, cli, rust
- tags: cargo, rust, unused-dependencies, linting, nightly, command-line, linux, macos
