cargo-clippy

A collection of lints to catch common mistakes and improve your Rust code.

TLDR

Run checks over the code in the current directory

$ cargo clippy

Require that Cargo.lock is up to date

$ cargo clippy --locked

Run checks on all packages in the workspace

$ cargo clippy --workspace

Run checks for a package

$ cargo clippy --package [package]

Treat warnings as errors

$ cargo clippy -- --deny warnings

Run checks and ignore warnings

$ cargo clippy -- --allow warnings

Apply Clippy suggestions automatically

$ cargo clippy --fix

Checks a package to catch common mistakes and improve your Rust code.

Usage:
    cargo clippy [options] [--] [...]

Common options:
    --no-deps                Run Clippy only on the given crate, without linting the dependencies
    --fix                    Automatically apply lint suggestions. This flag implies `--no-deps`
    -h, --help               Print this message
    -V, --version            Print version info and exit

Other options are the same as `cargo check`.

To allow or deny a lint from the command line you can use `cargo clippy --`
with:

    -W --warn OPT       Set lint warnings
    -A --allow OPT      Set lint allowed
    -D --deny OPT       Set lint denied
    -F --forbid OPT     Set lint forbidden

You can use tool lints to allow or deny lints from your code, eg.:

    #[allow(clippy::needless_lifetimes)]
