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`
