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
