rustfmt is the official Rust code formatter that formats Rust code according to standard style guidelines. It integrates with cargo via `cargo fmt` and can be used in CI to enforce consistent code style.

Use cases

  • format rust code
  • enforce rust style guidelines
  • run cargo fmt on a project
  • check code formatting in CI
  • auto-format rust files

When to choose

  • you write Rust and want consistent, idiomatic formatting
  • you want to enforce style checks in CI
  • you want the official Rust formatter maintained by the Rust project

When to avoid

  • your code relies heavily on macros or comments that rustfmt cannot format reliably
  • you need to format non-Rust languages
  • your code does not parse (rustfmt requires parseable code)
