Trait Implementations

impl BlockRngCore for ChaCha20Core[+]

[+] Show hidden undocumented items

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 ChaCha20Core[+]

[+] Show hidden undocumented items

fn clone(&self) -> ChaCha20Core[−]

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl CryptoRng for ChaCha20Core

impl Debug for ChaCha20Core[+]

[+] Show hidden undocumented items

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

Formats the value using the given formatter.

impl From<ChaCha20Core> for ChaCha20Rng[+]

[+] Show hidden undocumented items

fn from(core: ChaCha20Core) -> Self[−]

Performs the conversion.

impl SeedableRng for ChaCha20Core[+]

[+] Show hidden undocumented items

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.

fn from_entropy() -> Self[−]

Creates a new instance of the RNG seeded via getrandom.
