| error[E0382]: use of moved value | |
| --> $DIR/move-in-pattern-mut-in-loop.rs:7:21 | |
| | | |
| LL | if let Some(mut _x) = opt {} | |
| | ^^^^^^ value moved here, in previous iteration of loop | |
| | | |
| = note: move occurs because value has type `&mut i32`, which does not implement the `Copy` trait | |
| help: borrow this binding in the pattern to avoid moving the value | |
