Struct mx3::v3::Mx3Rng

pub struct Mx3Rng { /* private fields */ }

Pseudo-random number generator with 64-bits of state and cycle of 2^64.

This RNG is not cryptographically secure.

Implementations

impl Mx3Rng

pub fn new(seed: u64) -> Self

Creates the PRNG generator using the given seed.

This constructor modifies the seed before it is used in manner that is equivalent to the reference design constructor. Self::from_seed() uses a different seed mixing function.

pub fn resume(state: u64) -> Self

Creates the PRNG generator from an existing state.

pub fn state(&self) -> u64

Return the state of the generator.

The generator can be resumed by passing the state to Self::resume() constructor.

Trait Implementations

impl Clone for Mx3Rng

fn clone(&self) -> Mx3Rng

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Mx3Rng

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

Formats the value using the given formatter.

impl RngCore for Mx3Rng

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 Mx3Rng

type Seed = [u8; 8]

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.
