error[E0525]: expected a closure that implements the `Fn` trait, but this closure only implements `FnOnce`
|
|
--> $DIR/issue-26046-fn-once.rs:4:19
|
|
|
|
|
LL | let closure = move || {
|
|
| ^^^^^^^ this closure implements `FnOnce`, not `Fn`
|
|
LL | vec
|
|
| --- closure is `FnOnce` because it moves the variable `vec` out of its environment
|
|
...
|
|
LL | Box::new(closure)
|
|
| ----------------- the requirement to implement `Fn` derives from here
|
|
|
|
|
= note: required for the cast from `Box<{closure@$DIR/issue-26046-fn-once.rs:4:19: 4:26}>` to `Box<(dyn Fn() -> Vec<u8> + 'static)>`
