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 | ||
