| error[E0005]: refutable pattern in local binding |
| --> $DIR/feature-gate-exhaustive-patterns.rs:8:9 |
| | |
| LL | let Ok(_x) = &foo(); |
| | ^^^^^^ pattern `&Err(_)` 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 `&Result<u32, !>` |
| help: you might want to use `let else` to handle the variant that isn't matched |
| | |
| LL | let Ok(_x) = &foo() else { todo!() }; |
