What it is

rust-clippy is a linter for Rust that provides over 800 community-driven lints organized into 10 categories (correctness, suspicious, style, complexity, performance, pedantic, restriction, nursery, and cargo) with configurable warn/deny levels. It integrates with rustc to catch common mistakes, improve code idiomaticity, and optimize runtime performance across Rust projects. The core capability is compile-time static analysis delivered as a cargo clippy subcommand and a standalone clippy-driver binary. See architecture tab.

Start here

Read these in order:

  • clippy_lints/src/loops/mod.rs — Foundation: doesn't import anything internally and is imported by 1 other file. Read first to learn the vocabulary.
  • clippy_lints/src/matches/mod.rs — Foundation: imported by 1, no internal dependencies of its own.
  • clippy_lints/src/casts/mod.rs — Built on the foundation; imported by 1 downstream file.
  • clippy_lints/src/attrs/mod.rs — Built on the foundation; imported by 1 downstream file.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone and verify Cargo.toml setup: git clone https://github.com/rust-lang/rust-clippy.git && cd rust-clippy. Check Rust version requirements (edition = "2024" suggests a recent nightly or future stable). Verify the re…

Daily commands:

clippy-driver runs as a rustc wrapper: cargo +nightly install --path . --bin clippy-driver. cargo-clippy runs as a Cargo subcommand: cargo +nightly clippy (after cargo install --path . --bin cargo-clippy). For dev…

…shortened for this brief.

Key cautions & unknowns

  • Clippy requires rustc_private features (noted in package.metadata.rust-analyzer), which means it must be built with nightly Rust and may break between Rust versions without warning. The edition = "2024" in Cargo.toml…
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
