Implementations

impl<R: Rounds, V: Variant> ChaChaCore<R, V>

pub fn get_block_pos(&self) -> V::Counter

Get the current block position.

pub fn set_block_pos(&mut self, pos: V::Counter)

Set the block position.

Trait Implementations

impl<R: Rounds, V: Variant> Debug for ChaChaCore<R, V>

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

Formats the value using the given formatter.

impl<R: Rounds, V: Variant> Generator for ChaChaCore<R, V>

fn generate(&mut self, buffer: &mut [u32; 64])

Generates 4 blocks in parallel with avx2 & neon, but merely fills 4 blocks with sse2 & soft

type Output = [u32; 64]

The output type.

fn drop(&mut self, output: &mut Self::Output)

Destruct the output buffer

impl<R: Rounds, V: Variant> SeedableRng for ChaChaCore<R, V>

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: &mut R) -> Self

where R: Rng + ?Sized,

Create a new PRNG seeded from an infallible Rng.

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

where R: TryRng + ?Sized,

Create a new PRNG seeded from a potentially fallible Rng.
