3.2. Using rustfmt as a standalone tool

Prerequisites

• An existing Rust project.

Procedure

• Format the Rust source code:

  $ rustfmt <source-file>

  Replace <source_file> with the name of your source file. Alternatively, you can replace <source_file> with standard input. The rustfmt utility then provides its output in standard output.

  중요

  By default, rustfmt modifies the affected files without displaying details or creating backups. To display details and create backups, run rustfmt with the --write-mode option.
