| description.long | 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. | flake8 is an open-source Python linter that combines multiple style-checking tools to verify code compliance with PEP 8 and detect errors. It uses a plugin architecture for extensibility and is commonly integrated into development workflows and CI/CD pipelines. |
