| 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 |
| | |
| help: clone the value before moving it into the closure |
| | |
| LL ~ let value = bar.clone(); |
| LL ~ let _h = to_fn_once(move || -> isize { value }); |
