| error[E0507]: cannot move out of `*v`, as `v` is a captured variable in an `FnMut` closure | |
| --> $DIR/issue-4335.rs:6:20 | |
| | | |
| LL | fn f<'r, T>(v: &'r T) -> Box<dyn FnMut() -> T + 'r> { | |
| | - captured outer variable | |
| LL | id(Box::new(|| *v)) | |
| | ^^ move occurs because `*v` has type `T`, which does not implement the `Copy` trait | |
| error: aborting due to previous error | |
