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!() };
