| error[E0525]: expected a closure that implements the `Fn` trait, but this closure only implements `FnOnce` |
| --> $DIR/closure-wrong-kind.rs:20:19 |
| | |
| LL | let closure = |_| foo(x); //~ ERROR E0525 |
| | ^^^^^^^^-^ |
| | | | |
| | | 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 |
