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); //~ 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
