error[E0507]: cannot move out of `foo` in pattern guard
|
|
--> $DIR/issue-27282-mutation-in-guard.rs:8:18
|
|
|
|
|
LL | (|| { let bar = foo; bar.take() })();
|
|
| ^^ --- move occurs because `foo` has type `&mut Option<&i32>`, which does not implement the `Copy` trait
|
|
| |
|
|
| `foo` is moved here
|
|
|
|
|
= note: variables bound in patterns cannot be moved from until after the end of the pattern guard
|
|
help: consider cloning the value if the performance cost is acceptable
