Trait Implementations

impl From<ChaChaCore> for ChaChaRng

[+]

fn from(core: ChaChaCore) -> Self

[−]

Performs the conversion.

impl Clone for ChaChaCore

[+]

fn clone(&self) -> ChaChaCore

[−]

Returns a copy of the value.

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

[−]

Performs copy-assignment from source.

impl Debug for ChaChaCore

[+]

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

[−]

Formats the value using the given formatter.

impl SeedableRng for ChaChaCore

[+]

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.

impl BlockRngCore for ChaChaCore

[+]

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.
