Struct StandardSeedableRng 

pub struct StandardSeedableRng { /* private fields */ }

An RNG that generates values directly from a seed (similar to proptest’s PassThrough RNG). This is mostly only useful in conjunction with the provided distributions like [StandardBuffered] because although the [RandCore] trait is restrictive and only allows byte-level resolution, we want to do better than this.

Trait Implementations

impl Clone for StandardSeedableRng

fn clone(&self) -> StandardSeedableRng

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StandardSeedableRng

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

Formats the value using the given formatter.

impl RngCore for StandardSeedableRng

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 StandardSeedableRng

type Seed = Vec<u8>

Seed type, which is restricted to types mutably-dereferenceable 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.

fn from_entropy() -> Self

Creates a new instance of the RNG seeded via getrandom.
