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()
