| error[E0005]: refutable pattern in local binding: `A(_)` not covered |
| --> $DIR/uninhabited-irrefutable.rs:27:9 |
| | |
| LL | / enum Foo { |
| LL | | A(foo::SecretlyEmpty), |
| | | - not covered |
| LL | | B(foo::NotSoSecretlyEmpty), |
| LL | | C(NotSoSecretlyEmpty), |
| LL | | D(u32), |
| LL | | } |
| | |_- `Foo` defined here |
| ... |
| LL | let Foo::D(_y) = x; |
| | ^^^^^^^^^^ pattern `A(_)` not covered |
| | |
| = note: `let` bindings require an "irrefutable pattern", like a `struct` or an `enum` with only one variant |
| = note: for more information, visit https://doc.rust-lang.org/book/ch18-02-refutability.html |
| = note: the matched value is of type `Foo` |
| help: you might want to use `if let` to ignore the variant that isn't matched |
| | |
| LL | if let Foo::D(_y) = x { /* */ } |
| | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| |
| error: aborting due to previous error |
