42 /// Macro used to declare a Clippy lint.
44 /// Every lint declaration consists of 4 parts:
46 /// 1. The documentation, which is used for the website
47 /// 2. The `LINT_NAME`. See [lint naming][lint_naming] on lint naming conventions.
48 /// 3. The `lint_level`, which is a mapping from *one* of our lint groups to `Allow`, `Warn` or
49 /// `Deny`. The lint level here has nothing to do with what lint groups the lint is a part of.
50 /// 4. The `description` that contains a short explanation on what's wrong with code where the
51 /// lint is triggered.
53 /// Currently the categories `style`, `correctness`, `complexity` and `perf` are enabled by default.
54 /// As said in the README.md of this repository, if the lint level mapping changes, please update
