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
|
|
| |
|
|
| captured by this `FnMut` closure
|
|
|
|

help: if `T` implemented `Clone`, you could clone the value
