Struct rand_xoshiro::Xoroshiro64StarStar

pub struct Xoroshiro64StarStar { /* fields omitted */ }

A xoroshiro64** random number generator.

The xoshiro64** algorithm is not suitable for cryptographic purposes, but is very fast and has excellent statistical properties.

The algorithm used here is translated from the xoroshiro64starstar.c reference source code by David Blackman and Sebastiano Vigna.

Trait Implementations

impl Clone for Xoroshiro64StarStar

pub fn clone(&self) -> Xoroshiro64StarStar

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Xoroshiro64StarStar

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Xoroshiro64StarStar

impl PartialEq<Xoroshiro64StarStar> for Xoroshiro64StarStar

pub fn eq(&self, other: &Xoroshiro64StarStar) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &Xoroshiro64StarStar) -> bool

This method tests for !=.

impl RngCore for Xoroshiro64StarStar

pub fn next_u32(&mut self) -> u32

Return the next random u32.

pub fn next_u64(&mut self) -> u64

Return the next random u64.

pub fn fill_bytes(&mut self, dest: &mut [u8])

Fill dest with random data.

pub fn try_fill_bytes(&mut self, dest: &mut [u8]) -> Result<(), Error>

Fill dest entirely with random data.

impl SeedableRng for Xoroshiro64StarStar

type Seed = [u8; 8]

Seed type, which is restricted to types mutably-dereferencable as u8 arrays (we recommend [u8; N] for some N).

pub fn from_seed(seed: [u8; 8]) -> Xoroshiro64StarStar

Create a new Xoroshiro64StarStar. If seed is entirely 0, it will be mapped to a different seed.

pub fn seed_from_u64(seed: u64) -> Xoroshiro64StarStar

Seed a Xoroshiro64StarStar from a u64 using SplitMix64.

pub fn from_rng<R>(rng: R) -> Result<Self, Error> where
    R: RngCore, 

Create a new PRNG seeded from another Rng.
