57 /// 1. The documentation, which is used for the website
58 /// 2. The `LINT_NAME`. See [lint naming][lint_naming] on lint naming conventions.
59 /// 3. The `lint_level`, which is a mapping from *one* of our lint groups to `Allow`, `Warn` or
60 /// `Deny`. The lint level here has nothing to do with what lint groups the lint is a part of.

62 /// lint is triggered.
64 /// Currently the categories `style`, `correctness`, `complexity` and `perf` are enabled by default.
