Type Definition permutator::KPermutationParams

type KPermutationParams<'a, T> = (&'a [T], usize);

A pair of parameter that allow Permutation trait to create k-permutation iterator from it.

This type is used exclusively in trait Permutation

Format

1. First value in tuple is &'a [T]. It's a source data to generate k-permutation.
2. Second value in tuple is usize. It's k size which shall be less than n where n is a length of the first value.

Trait Implementations

impl<'a, T> Permutation<'a> for KPermutationParams<'a, T>

type Permutator = KPermutationIterator<'a, T>

A permutation generator for a collection of data. # See - Foreign implementation for an example different return type

Important traits for KPermutationIterator<'a, T>
