error[E0525]: expected a closure that implements the `Fn` trait, but this closure only implements `FnOnce`
--> $DIR/closure-origin-array-diagnostics.rs:9:13
|
LL | let c = || {
| ^^ this closure implements `FnOnce`, not `Fn`
LL | let [_, _s] = s;
| - closure is `FnOnce` because it moves the variable `s` out of its environment
LL | };
LL | expect_fn(c);
| --------- - the requirement to implement `Fn` derives from here
| |
| required by a bound introduced by this call
|
note: required by a bound in `expect_fn`
--> $DIR/closure-origin-array-diagnostics.rs:5:17
|
LL | fn expect_fn<F: Fn()>(_f: F) {}
| ^^^^ required by this bound in `expect_fn`
error: aborting due to previous error
