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)
