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
|
LL | if let Some(ref mut _x) = opt {}
