rustfmt is the tool for Rust coding style.

Run Locally

The mozlint integration of rustfmt can be run using mach:

$ mach lint --linter rustfmt <file paths>


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


Rustfmt is reformatting the code by default. To highlight the results, we are using the --check option.
