Struct pcg_rand::PcgEngine

pub struct PcgEngine<Itype, Xtype, StreamMix: Stream<Itype>, MulMix: Multiplier<Itype>, OutMix: OutputMixin<Itype, Xtype>> { /* fields omitted */ }

A generic PCG structure.

This structure allows the building of many types of PCG generators by using various Mixins for both the stream, multiplier, and permutation function.

Methods

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.

fn next_u32(&mut self) -> u32

Return the next random u32.

fn next_u64(&mut self) -> u64

type Seed = PcgSeeder<Itype>

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

Create a new PRNG seeded from another Rng.
