Available on crate feature combinations_with_reps only.
Expand description

An extension trait that provides the combinations_with_reps method for iterators.

Provided Methods§

source

fn combinations_with_reps(self, k: usize) -> CombinationsWithReps<Self> ⓘ
where Self: Sized, Self::Item: Clone,

Returns an iterator adaptor that iterates over k length combinations with repetitions/replacements of all the elements in the underlying iterator.

The iterator is consumed as elements are required.

Panics

If called with k = 0.

Examples

Basic usage:

use itermore::IterCombinationsWithReps;

let mut iter = "ab".chars().combinations_with_reps(3);
assert_eq!(iter.next(), Some(vec!['a', 'a', 'a']));
assert_eq!(iter.next(), Some(vec!['a', 'a', 'b']));
assert_eq!(iter.next(), Some(vec!['a', 'b', 'a']));
assert_eq!(iter.next(), Some(vec!['a', 'b', 'b']));
assert_eq!(iter.next(), Some(vec!['b', 'a', 'a']));
// etc
