Struct chacha20::ChaCha12RngCore

pub struct ChaCha12RngCore { /* fields omitted */ }

This is supported on feature="rng" only.

Core random number generator, for use with rand_core::block::BlockRng

Trait Implementations

impl BlockRngCore for ChaCha12RngCore

type Item = u32

Results element type, e.g. u32.

type Results = [u32; 16]

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

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

Generate a new block of results.

impl Clone for ChaCha12RngCore

fn clone(&self) -> ChaCha12RngCore

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CryptoRng for ChaCha12RngCore

impl Debug for ChaCha12RngCore

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

Formats the value using the given formatter.

impl SeedableRng for ChaCha12RngCore

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.
