…flip1995 Improvement for `equatable_if_let` fixes rust-lang#9221 This PR makes sure that enums or structs not implementing `PartialEq` trait but still using the `if let` patterns can be linted to be rewritten with `matches!`. If you added a new lint, here's a checklist for things that will be checked during review or continuous integration. - \[ ] Followed [lint naming conventions][lint_naming] - \[x] Added passing UI tests (including committed `.stderr` file) - \[x] `cargo test` passes locally - \[ ] Executed `cargo dev update_lints` - \[ ] Added lint documentation - \[x] Run `cargo dev fmt` --- changelog: Improve [`equatable_if_let`] with additional `matches!` suggestions.
