clippy is the tool for Rust static analysis.

Run Locally

The mozlint integration of clippy can be run using mach:

$ mach lint --linter clippy <file paths>


clippy expects a path or a .rs file. It doesn’t accept Cargo.toml as it would break the mozlint workflow.


To enable clippy on new directory, add the path to the include section in the clippy.yml file.


This linter provides a --fix option. It requires using nightly which can be installed with:

$ rustup component add clippy --toolchain nightly-x86_64-unknown-linux-gnu
