[][src]Struct itertools::structs::Groups

#[must_use = "iterator adaptors are lazy and do nothing unless consumed"]
pub struct Groups<'a, K: 'a, I: 'a, F: 'a> where
    I: Iterator,
    I::Item: 'a, 
{ /* fields omitted */ }

An iterator that yields the Group iterators.

Iterator element type is (K, Group): the group's key K and the group's iterator.

See .group_by() for more information.
