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 field in the pattern to avoid moving `opt.0` | |
| | |
LL | if let Some(ref mut _x) = opt {} | |
| ^^^ | |
error: aborting due to previous error | |
