error[E0004]: non-exhaustive patterns: `Some(_)` not covered
--> $DIR/nested-non-exhaustive-enums.rs:8:11

LL | match Some(NonExhaustiveEnum::A) {
| ^^^^^^^^^^^^^^^^^^^^^^^^^^ pattern `Some(_)` not covered

note: `Option<NonExhaustiveEnum>` defined here

= note: not covered
= note: the matched value is of type `Option<NonExhaustiveEnum>`
= note: `NonExhaustiveEnum` is marked as non-exhaustive, so a wildcard `_` is necessary to match exhaustively
help: ensure that all possible cases are being handled by adding a match arm with a wildcard pattern or an explicit pattern as shown
