Struct pcg_mwc::Mwc128XXA32

pub struct Mwc128XXA32 { /* fields omitted */ }

A PCG random number generator (MWC X A 128/32 variant).

Permuted Congruential Generator with 128-bit state, internal multiply with carry Generator, and 32-bit output via a xor and an add.

Implementations

impl Mwc128XXA32

pub fn new(k1: u32, k2: u32) -> Self

Construct an instance given two keys.

pub fn next(&mut self) -> u32

Trait Implementations

impl Clone for Mwc128XXA32

fn clone(&self) -> Mwc128XXA32

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Mwc128XXA32> for Mwc128XXA32

fn eq(&self, other: &Mwc128XXA32) -> bool

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

fn ne(&self, other: &Mwc128XXA32) -> bool

This method tests for !=.

impl RngCore for Mwc128XXA32

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.

impl SeedableRng for Mwc128XXA32

We use a single 121-bit seed to initialise the state and select a stream. Of the 128 seed bits 7 are ignored.

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: Self::Seed) -> 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.
