error[E0191]: the value of the associated type `Item` (from trait `Iterator`) must be specified
--> $DIR/trait-hidden-method.rs:6:33

LL | Box::new(1..=10) as Box<dyn Iterator>
| ^^^^^^^^ help: specify the associated type: `Iterator<Item = Type>`
error[E0271]: expected `Box<dyn Iterator>` to be an iterator that yields `u32`, but it yields `<dyn Iterator as Iterator>::Item`
--> $DIR/trait-hidden-method.rs:3:32

LL | pub fn i_can_has_iterator() -> impl Iterator<Item = u32> {
| ^^^^^^^^^^^^^^^^^^^^^^^^^ expected associated type, found `u32`

LL | Box::new(1..=10) as Box<dyn Iterator>
| ------------------------------------- return type was inferred to be `Box<dyn Iterator>` here

= note: expected associated type `<dyn Iterator as Iterator>::Item`
found type `u32`
= help: consider constraining the associated type `<dyn Iterator as Iterator>::Item` to `u32` or calling a method that returns `<dyn Iterator as Iterator>::Item`
