/// Macro used to declare a Clippy lint.
///
/// Every lint declaration consists of 4 parts:
///
/// 1. The documentation, which is used for the website
/// 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`, `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
///
/// ```
/// #![feature(rustc_private)]
/// extern crate rustc_session;
/// use rustc_session::declare_tool_lint;
/// use clippy_lints::declare_clippy_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.
/// ///
/// /// **Known problems:** None. (Or describe where it could go wrong.)
/// ///
/// /// **Example:**
/// ///
/// /// ```rust
/// /// // Bad
/// /// Insert a short example of code that triggers the lint
/// ///
/// /// // Good
/// /// Insert a short example of improved code that doesn't trigger the lint
/// /// ```
/// pub LINT_NAME,
