error[E0382]: use of moved value: `x`
|
|
--> $DIR/liveness-move-call-arg.rs:9:14
|
|
|
|
|
LL | let x: Box<isize> = Box::new(25);
|
|
| - move occurs because `x` has type `Box<isize>`, which does not implement the `Copy` trait
|
|
LL |
|
|
LL | loop {
|
|
| ---- inside of this loop
|
|
LL | take(x);
|
|
| ^ value moved here, in previous iteration of loop
|
|
|
|
|
note: consider changing this parameter type in function `take` to borrow instead if owning the value isn't necessary
|
|
--> $DIR/liveness-move-call-arg.rs:1:13
|
|
|
|
|
LL | fn take(_x: Box<isize>) {}
|
|
| ---- ^^^^^^^^^^ this parameter takes ownership of the value
|
|
| |
|
|
| in this function
|
|
help: consider cloning the value if the performance cost is acceptable
|
|
|
|
|
LL | take(x.clone());
