rustfmt

Tool for formatting 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}}
