error[E0525]: expected a closure that implements the `Fn` trait, but this closure only implements `FnOnce`

--> $DIR/unboxed-closures-infer-fn-once-move-from-projection.rs:14:13
|
|
|
|
|
LL | let c = || drop(y.0);
|
|
| ^^ --- closure is `FnOnce` because it moves the variable `y` out of its environment
|
|
| |
|
|
| this closure implements `FnOnce`, not `Fn`
|
|
LL | foo(c);
|
|
| --- - the requirement to implement `Fn` derives from here
|
|
| |
|
|
| required by a bound introduced by this call

note: required by a bound in `foo`
