Struct xoroshiro128::Xoroshiro128Rng

pub struct Xoroshiro128Rng { /* fields omitted */ }

Methods

impl Xoroshiro128Rng

pub fn new_unseeded() -> Self

Creates a new Xoroshiro128Rng instance which is not seeded.

The initial values of this Rng are constants, so all generators created by this function will yield the same stream of random numbers. It is highly recommended that this is created through SeedableRng instead of this function.

pub fn from_seed_u64(seed: [u64; 2]) -> Self

Trait Implementations

impl Debug for Xoroshiro128Rng

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Copy for Xoroshiro128Rng

impl Clone for Xoroshiro128Rng

fn clone(&self) -> Xoroshiro128Rng

Returns a copy of the value.

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

Performs copy-assignment from source.

impl SeedableRng for Xoroshiro128Rng

Seed a Xoroshiro128Rng with a given seed.

Panics

Xoroshiro128Rng is undefined for the seed [0, 0] and will panic if this seed is provided.

type Seed = [u8; 16]

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

fn from_seed(seed: [u8; 16]) -> Self

Create a new PRNG using the given seed.

fn seed_from_u64(state: u64) -> Self

Create a new PRNG using a u64 seed.

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

Create a new PRNG seeded from another Rng.

impl RngCore for Xoroshiro128Rng

fn next_u32(&mut self) -> u32

Return the next random u32.

fn next_u64(&mut self) -> u64

Return the next random u64.

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

Fill dest with random data.

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

Fill dest entirely with random data.
