 Lints are divided into categories, each with a default [lint level](https://doc.rust-lang.org/rustc/lints/levels.html).
 You can choose how much Clippy is supposed to ~~annoy~~ help you by changing the lint level by category.
 
-Category | Description | Default level
--- | -- | --
-`clippy::all` | all lints that are on by default (correctness, style, complexity, perf) | **warn/deny**
