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`
--> $DIR/unboxed-closures-infer-fn-once-move-from-projection.rs:4:14
|
LL | fn foo<F>(f: F)
| --- required by a bound in this function
LL | where F: Fn()
| ^^^^ required by this bound in `foo`
