error[E0382]: use of moved value: `x`
|
|
--> $DIR/move-guard-same-consts.rs:20:24
|
|
|
|
|
LL | let x: Box<_> = Box::new(1);
|
|
| - move occurs because `x` has type `Box<i32>`, which does not implement the `Copy` trait
|
|
...
|
|
LL | (1, 2) if take(x) => (),
|
|
| - value moved here
|
|
LL | (1, 2) if take(x) => (),

|
| ^ value used here after move
|
|
|
|
|
note: consider changing this parameter type in function `take` to borrow instead if owning the value isn't necessary

help: consider cloning the value if the performance cost is acceptable
