Trait ep_core::random_permutation::RandomPermutation

pub trait RandomPermutation {
    type Item;

    // Required method
    fn random_permutation<Hashing: Hash>(
        self,
        random: &mut RandomNumberGenerator<Hashing>
    ) -> Option<Vec<Self::Item>>;
}

Pseudo-random permutation. It’s as secure as the combination of the seed with which the RandomNumberGenerator is constructed and the hash function it uses to cycle the elements.

Required Methods

fn random_permutation<Hashing: Hash>( self, random: &mut RandomNumberGenerator<Hashing> ) -> Option<Vec<Self::Item>>

Random permutation from an array of elements. This is guaranteed to return Some except in the case that self is empty.
