Clippy is a linting tool for Rust that helps developers catch common mistakes, spot non-idiomatic code, and improve code quality across projects.
It integrates with the standard Rust toolchain, is installed as a rustup component, and is typically run with Cargo during development and continuous integration workflows.
This is free and open source software.
Key Features
- Provides more than 800 lints for Rust code.
- Organizes lints into categories such as correctness, suspicious, style, complexity, perf, pedantic, restriction, nursery, and cargo.
- Lets developers control whether lints are allowed, warned on, or denied by lint group or individual lint.
- Can automatically apply some suggested fixes with
cargo clippy --fix. - Works with Cargo workspaces and also supports running through
clippy-driverfor non-Cargo projects. - Supports configuration through
clippy.tomlor.clippy.tomlfor selected lint behavior.
