Struct chacha20::ChaCha8Rng

pub struct ChaCha8Rng(_);

Random number generator over the ChaCha8 stream cipher.

Trait Implementations

impl Clone for ChaCha8Rng

fn clone(&self) -> ChaCha8Rng

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CryptoRng for ChaCha8Rng

impl Debug for ChaCha8Rng

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

Formats the value using the given formatter.

impl RngCore for ChaCha8Rng

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, bytes: &mut [u8])

Fill dest with random data.

fn try_fill_bytes(&mut self, bytes: &mut [u8]) -> Result<(), Error>

Fill dest entirely with random data.

impl SeedableRng for ChaCha8Rng

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.

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.
