rustfmt Command Examples

Format Rust source code. More information: https://github.com/rust-lang/rustfmt.

• Format a file, overwriting the original file in-place:

rustfmt {{path/to/source.rs}}

• Check a file for formatting and display any changes on the console:

rustfmt --check {{path/to/source.rs}}

• Backup any modified files before formatting (the original file is renamed with a .bk extension):

rustfmt --backup {{path/to/source.rs}}
