| 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 3; |
| | --- captured outer variable |
| LL | let _g = to_fn_mut(|| { |
| LL | let _h = to_fn_once(move || -> isize { *bar }); |
| | ^^^^^^^^^^^^^^^^ --- |
| | | | |
| | | move occurs because `bar` has type `std::boxed::Box<isize>`, which does not implement the `Copy` trait |
| | | move occurs due to use in closure |
| | move out of `bar` occurs here |
| |
| error: aborting due to previous error |
