| 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` |
