pub struct Permutation<B = DefaultBuildHasher>
where
    B: BuildHasher,
{ /* private fields */ }

An object of constructing random access permutations.

Implementations

impl<B> Permutation<B>

where B: BuildHasher,

pub fn new(n: u64, seed: u64, bob: B) -> Permutation<B>

Construct a new permutation over the range 0..n.

pub fn get(&self, x: u64) -> u64

Get the xth element of the permutation.

pub fn iter(&self) -> PermutationIterator<'_, B>

Construct an iterator over the entire permutation.

pub fn range(&self, begin: u64, end: u64) -> PermutationIterator<'_, B>

Construct an iterator over the subset begin..end of the permutation.
