ChaCha with 20 rounds

Trait Implementations

impl BlockRngCore for ChaCha20Core

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

fn clone(&self) -> ChaCha20Core

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChaCha20Core

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

Formats the value using the given formatter.

impl From<ChaCha20Core> for ChaCha20Rng

fn from(core: ChaCha20Core) -> Self

Converts to this type from the input type.

impl PartialEq for ChaCha20Core

fn eq(&self, other: &ChaCha20Core) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SeedableRng for ChaCha20Core

type Seed = [u8; 32]

Seed type, which is restricted to types mutably-dereferenceable 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
