error[E0507]: cannot move out of `bar`, a captured variable in an `FnMut` closure
|
|
--> $DIR/borrowck-move-by-capture.rs:9:29
|
|
|
|
|
LL | let bar: Box<_> = Box::new(3);
|
|
| --- captured outer variable
|
|
LL | let _g = to_fn_mut(|| {
|
|
| -- captured by this `FnMut` closure
|
|
LL | let _h = to_fn_once(move || -> isize { *bar });
|
|
| ^^^^^^^^^^^^^^^^ ----
|
|
| | |
|
|
| | variable moved due to use in closure
|
|
| | move occurs because `bar` has type `Box<isize>`, which does not implement the `Copy` trait
|
|
| `bar` is moved here
|
