cargo-machete is a Cargo subcommand that quickly detects unused dependencies in Rust projects by scanning source code for dependency names. It is fast but imprecise, with configuration options to ignore false positives and a CI-friendly exit code.

Use cases

• find unused dependencies in a rust project
• clean up cargo.toml dependencies
• check for unused crates in ci
• detect dependencies that are no longer imported
• reduce compile time by removing unused deps

When to choose

• you want a fast, dependency-free scan of unused Rust dependencies
• you want a simple CI check via exit codes
• you maintain many Rust crates and want quick hygiene checks

When to avoid

• you need fully accurate analysis including build.rs-generated code without extra flags
• you need cross-language dependency analysis
• you cannot tolerate possible false positives without configuration
