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** |
| `clippy::correctness` | code that is outright wrong or very useless | **deny** |
| `clippy::style` | code that should be written in a more idiomatic way | **warn** |
| `clippy::complexity` | code that does something simple but in a complex way | **warn** |
| `clippy::perf` | code that can be written to run faster | **warn** |
| `clippy::pedantic` | lints which are rather strict or might have false positives | allow |
| `clippy::nursery` | new lints that are still under development | allow |
| `clippy::cargo` | lints for the cargo manifest | allow |

| `clippy::correctness` | code that is outright wrong or useless | **deny** |
