Struct rand_chacha::ChaCha8Core

pub struct ChaCha8Core { /* fields omitted */ }

ChaCha with 8 rounds

Trait Implementations

impl BlockRngCore for ChaCha8Core

type Item = u32

Results element type, e.g. u32.

type Results = Array64<u32>

Results type. This is the ‘block’ an RNG implementing BlockRngCore generates, which will usually be an array like [u32; 16].

fn generate(&mut self, r: &mut Self::Results)

Generate a new block of results.

impl Clone for ChaCha8Core

fn clone(&self) -> ChaCha8Core

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChaCha8Core

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

Formats the value using the given formatter.

impl From<ChaCha8Core> for ChaCha8Rng

fn from(core: ChaCha8Core) -> Self

Performs the conversion.

impl SeedableRng for ChaCha8Core

type Seed = [u8; 32]

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.

pub fn seed_from_u64(state: u64) -> Self

Create a new PRNG using a u64 seed.

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

Create a new PRNG seeded from another Rng.

pub fn from_entropy() -> Self

Creates a new instance of the RNG seeded via getrandom.
