| 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 | |
| error: aborting due to previous error | |
