Rust コードフォーマッタ

Format your Rust code following official rustfmt conventions. Paste your code, configure formatting options, and get clean, consistently styled output matching cargo fmt standards.

使い方

Paste your Rust code into the editor, select your preferred max line width (80, 100, or 120 characters) and Rust edition (2015, 2018, or 2021), then click Format. The formatted output appears with syntax highlighting, ready to copy or download as a .rs file.
