54 /// Every lint declaration consists of 4 parts:
56 /// 1. The documentation, which is used for the website
57 /// 2. The `LINT_NAME`. See [lint naming][lint_naming] on lint naming conventions.
58 /// 3. The `lint_level`, which is a mapping from *one* of our lint groups to `Allow`, `Warn` or
59 /// `Deny`. The lint level here has nothing to do with what lint groups the lint is a part of.
60 /// 4. The `description` that contains a short explanation on what's wrong with code where the
61 /// lint is triggered.
63 /// Currently the categories `style`, `correctness`, `complexity` and `perf` are enabled by default.
