| warning[E0507]: cannot move out of `foo` in pattern guard |
| --> $DIR/borrowck-migrate-to-nll.rs:25:18 |
| | |
| LL | (|| { let bar = foo; bar.take() })(); |
| | ^^ --- |
| | | | |
| | | move occurs because `foo` has type `&mut std::option::Option<&i32>`, which does not implement the `Copy` trait |
| | | move occurs due to use in closure |
| | move out of `foo` occurs here |
| | |
| = note: variables bound in patterns cannot be moved from until after the end of the pattern guard |
| = warning: this error has been downgraded to a warning for backwards compatibility with previous releases |
| = warning: this represents potential undefined behavior in your code and this warning will become a hard error in the future |
| = note: for more information, try `rustc --explain E0729` |
