HasIterator<V> trait?

1

Is there a way to formulate a trait for "HasIterator" ?

I.e.

T: HasIterator<V> if and only if T.iter() exists and has type Iterator<Item = V> ?

==================================

Context: I am trying to write generic code that says: you can pass any object here where we can call '.iter()" on.
