error[E0525]: expected a closure that implements the `Fn` trait, but this closure only implements `FnOnce`
|
|
--> $DIR/closure-wrong-kind.rs:10:19
|
|
|
|
|
LL | let closure = |_| foo(x);
|
|
| ^^^ - closure is `FnOnce` because it moves the variable `x` out of its environment
|
|
| |
|
|
| this closure implements `FnOnce`, not `Fn`
|
|
LL | bar(closure);
|
|
| --- ------- the requirement to implement `Fn` derives from here
|
|
| |
|
|
| required by a bound introduced by this call
|
|
|
|
|
note: required by a bound in `bar`
|

--> $DIR/closure-wrong-kind.rs:6:11

|
LL | fn bar<T: Fn(u32)>(_: T) {}
|
|
| ^^^^^^^ required by this bound in `bar`
