| 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[E0373]: closure may outlive the current function, but it borrows `v`, which is owned by the current function |
| --> $DIR/issue-4335.rs:6:17 |
| | |
| LL | id(Box::new(|| *v)) |
| | ^^ - `v` is borrowed here |
| | | |
| | may outlive borrowed value `v` |
| | |
| note: closure is returned here |
| --> $DIR/issue-4335.rs:6:5 |
| | |
| LL | id(Box::new(|| *v)) |
| | ^^^^^^^^^^^^^^^^^^^ |
| help: to force the closure to take ownership of `v` (and any other referenced variables), use the `move` keyword |
| | |
| LL | id(Box::new(move || *v)) |
| | ^^^^^^^ |
