cargo-clippy

name	cargo-clippy
description	Lint Rust code with clippy. Use before committing, reviewing, or when checking code quality. Catches style issues, common mistakes, and suboptimal patterns beyond what the compiler finds.

Linting

cargo clippy --workspace -- -D warnings

Fix

cargo clippy --workspace --fix --allow-dirty

Specific package

cargo clippy -p <package> -- -D warnings

Gotchas

• Always use -D warnings — without it, clippy prints warnings but exits 0, hiding problems.
• Run cargo fmt --check before clippy: cargo fmt --check && cargo clippy --workspace -- -D warnings.
• --fix --allow-dirty auto-applies fixable lints without requiring a clean git tree.
• Do NOT add suppressions (#[allow(...)], #[expect(...)], // clippy::..., --allow-dirty) to silence lints. Fix the root cause instead.
