/// The `indirect_structural_match` lint detects a `const` in a pattern
/// that manually implements [`PartialEq`] and [`Eq`].
///
/// [`PartialEq`]: https://doc.rust-lang.org/std/cmp/trait.PartialEq.html
/// [`Eq`]: https://doc.rust-lang.org/std/cmp/trait.Eq.html
///
/// ### Example
///
/// ```rust,compile_fail
/// #![deny(indirect_structural_match)]
///
/// struct NoDerive(i32);
/// impl PartialEq for NoDerive { fn eq(&self, _: &Self) -> bool { false } }
/// impl Eq for NoDerive { }
/// #[derive(PartialEq, Eq)]
/// struct WrapParam<T>(T);
/// const WRAP_INDIRECT_PARAM: & &WrapParam<NoDerive> = & &WrapParam(NoDerive(0));
/// fn main() {
/// match WRAP_INDIRECT_PARAM {
/// WRAP_INDIRECT_PARAM => { }
/// _ => { }
/// }
/// }
/// ```
///
/// {{produces}}
///
/// ### Explanation
///
/// The compiler unintentionally accepted this form in the past. This is a
/// [future-incompatible] lint to transition this to a hard error in the
/// future. See [issue #62411] for a complete description of the problem,
/// and some possible solutions.
///
/// [issue #62411]: https://github.com/rust-lang/rust/issues/62411
/// [future-incompatible]: ../index.md#future-incompatible-lints
