Struct ChaCha20Core

pub struct ChaCha20Core { /* private fields */ }

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 <ChaCha20Core as BlockRngCore>::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<(), Error>

Formats the value using the given formatter.

impl From<ChaCha20Core> for ChaCha20Rng

fn from(core: ChaCha20Core) -> ChaCha20Rng

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: <ChaCha20Core as SeedableRng>::Seed) -> ChaCha20Core

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(rng: &mut impl RngCore) -> Self

Create a new PRNG seeded from an infallible Rng.

fn try_from_rng<R>(rng: &mut R) -> Result<Self, <R as TryRngCore>::Error>

where R: TryRngCore,

Create a new PRNG seeded from a potentially fallible Rng.

fn from_os_rng() -> Self

Creates a new instance of the RNG seeded via getrandom.

fn try_from_os_rng() -> Result<Self, Error>

Creates a new instance of the RNG seeded via getrandom without unwrapping potential getrandom errors.
