| description.long | An opinionated Python code formatter that automatically reformats code according to a standardized style. It produces minimal diffs for cleaner code review and reduces developer cognitive load by removing formatting decisions, allowing focus on code logic. | Clippy provides over 800 lints organized into configurable categories to catch common mistakes and improve Rust code quality. Lints are categorized by severity (correctness, suspicious, style, complexity, performance) and can be enabled or disabled individually. |
