Struct Product
#[must_use = "iterator adaptors are lazy and do nothing unless consumed"]
pub struct Product<I, J>
where
I: Iterator, { /* private fields */ }An iterator adaptor that iterates over the cartesian product of
the element sets of two iterators I and J.
Iterator element type is (I::Item, J::Item).
See .cartesian_product() for more information.
