Struct Groups
#[must_use = "iterator adaptors are lazy and do nothing unless consumed"]
pub struct Groups<'a, K, I, F>
where
I: Iterator + 'a,
I::Item: 'a,
K: 'a,
F: 'a, { /* private fields */ }An iterator that yields the Group iterators.
Iterator element type is (K, Group):
the group's key K and the group's iterator.
See .chunk_by() for more information.
