| error[E0005]: refutable pattern in local binding: `Err(_)` not covered |
| --> $DIR/feature-gate-exhaustive-patterns.rs:6:9 |
| | |
| 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 |
| help: you might want to use `if let` to ignore the variant that isn't matched |
| | |
| LL | if let Ok(_x) = foo() { /* */ } |
| | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| |
| error: aborting due to previous error |
