Available on crate feature array_combinations_with_reps only.
Expand description

An extension trait that provides the array_combinations_with_reps method for iterators.

Provided Methods§

source

fn array_combinations_with_reps<const K: usize>( self ) -> ArrayCombinationsWithReps<Self, K> ⓘ
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::IterArrayCombinationsWithReps;

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