rustfmt is a formatter for Rust.

You can enable the rustfmt formatter with:

trunk check enable rustfmt

Auto Enabling

rustfmt will be auto-enabled if any Rust files are present.


rustfmt supports the following config files:

  • rustfmt.toml

  • .rustfmt.toml

You can move these files to .trunk/configs and trunk check will still find them. See Moving Linter Configs for more info. Trunk check provides a default .rustfmt.toml if your project does not already have one.

Usage Notes

We currently use the version of rustfmt packaged with rust, so for rustfmt version, specify your Rust version (for example rustfmt@1.61.0).

If you have edition in your cargo.toml, rustfmt also needs the same information in .rustfmt.toml in your repo root. For example, your .rustfmt.toml might contain:

edition = "2021"
