error[E0277]: the size for values of type `dyn Iterator<Item = &'a mut u8>` cannot be known at compilation time
--> $DIR/issue-20605.rs:2:17
|
LL | for item in *things { *item = 0 }
| ^^^^^^^ the trait `IntoIterator` is not implemented for `dyn Iterator<Item = &'a mut u8>`
|
= note: the trait bound `dyn Iterator<Item = &'a mut u8>: IntoIterator` is not satisfied
= note: required for `dyn Iterator<Item = &'a mut u8>` to implement `IntoIterator`
help: consider mutably borrowing here

LL | for item in &mut *things { *item = 0 }
