error[E0507]: cannot move out of `x` which is behind a mutable reference
--> $DIR/closure-shim-borrowck-error.rs:10:18
|
LL | needs_fn_mut(async || {
| ^^^^^^^^ `x` is moved here
LL |
LL | x.hello();
| -
| |
| variable moved due to use in coroutine
| move occurs because `x` has type `Ty`, which does not implement the `Copy` trait
|
note: if `Ty` implemented `Clone`, you could clone the value
--> $DIR/closure-shim-borrowck-error.rs:16:1
|
LL | x.hello();
| - you could clone this value
...
LL | struct Ty;
| ^^^^^^^^^ consider implementing `Clone` for this type
