Trait IteratorItemOrDefault

pub trait IteratorItemOrDefault<'borr>: InterfaceType {
    type Item;
}

Gets the expected Iterator::Item type for an InterfaceType, defaulting to () if it doesn’t require Iterator to be implemented.

Used by DynTrait’s vtable to give its iterator methods a defaulted return type.
