-/// Macro used to declare a Clippy lint.
-///
-/// Every lint declaration consists of 4 parts:
-///
-/// 1. The documentation, which is used for the website and `cargo clippy --explain`
-/// 2. The `LINT_NAME`. See [lint naming][lint_naming] on lint naming conventions.
-/// 3. The `lint_level`, which is a mapping from *one* of our lint groups to `Allow`, `Warn` or
-///    `Deny`. The lint level here has nothing to do with what lint groups the lint is a part of.
-/// 4. The `description` that contains a short explanation on what's wrong with code where the lint
-///    is triggered.
-///
-/// Currently the categories `style`, `correctness`, `suspicious`, `complexity` and `perf` are
-/// enabled by default. As said in the README.md of this repository, if the lint level mapping
-/// changes, please update README.md.
-///
-/// # Example
-///
-/// ```ignore
-/// use rustc_session::declare_tool_lint;
-///
-/// declare_clippy_lint! {
-///     /// ### What it does
-///     /// Checks for ... (describe what the lint matches).
-///     ///
-///     /// ### Why is this bad?
-///     /// Supply the reason for linting the code.
-///     ///
-///     /// ### Example
-///     /// ```rust
-///     /// Insert a short example of code that triggers the lint
-///     /// ```
-///     ///
-///     /// Use instead:
-///     /// ```rust
-///     /// Insert a short example of improved code that doesn't trigger the lint
-///     /// ```
-///     #[clippy::version = "1.65.0"]
-///     pub LINT_NAME,
-///     pedantic,
-///     "description"
-/// }
