non_exhaustive_omitted_patterns should not warn matches! macro #117304
Description
I tried this code:
#![feature(non_exhaustive_omitted_patterns_lint)] #![warn(non_exhaustive_omitted_patterns)] use std::sync::atomic::Ordering; // #[non_exhaustive] enum pub fn is_seqcst(order: Ordering) -> bool { matches!(order, Ordering::SeqCst) }I expected to see this happen: no warning
Instead, this happened:
warning: some variants are not matched explicitly --> src/lib.rs:7:14 | 7 | matches!(order, Ordering::SeqCst) | ^^^^^ patterns `std::sync::atomic::Ordering::Relaxed`, `std::sync::atomic::Ordering::Release`, `std::sync::atomic::Ordering::Acquire` and 1 more not covered | = help: ensure that all variants are matched explicitly by adding the suggested match arms = note: the matched value is of type `std::sync::atomic::Ordering` and the `non_exhaustive_omitted_patterns` attribute was found Meta
