Struct ChaCha20Rng 

pub struct ChaCha20Rng { /* private fields */ }

A deterministic ChaCha20 generator seeded entirely by its caller.

This type never obtains operating-system entropy. A caller that uses it for cryptography must provide a fresh, unpredictable 32-byte seed and must not reuse that seed across independent generator instances.

The generator intentionally does not implement Clone: duplicating a stream state can repeat nonces or key material.

use dcrypt_internal::random::ChaCha20Rng;
let generator = ChaCha20Rng::from_seed([7u8; 32]);
let duplicate = generator.clone();

Implementations

impl ChaCha20Rng

pub fn from_seed(seed: [u8; 32]) -> Self

Trait Implementations

impl CryptoRng for ChaCha20Rng

impl Drop for ChaCha20Rng

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl RngCore for ChaCha20Rng

fn try_fill_bytes(&mut self, destination: &mut [u8]) -> Result<(), Error>

Fill destination, propagating failures from the caller’s entropy source rather than silently substituting weak randomness.

fn next_u32(&mut self) -> u32

fn next_u64(&mut self) -> u64

fn fill_bytes(&mut self, destination: &mut [u8])

impl Zeroize for ChaCha20Rng

fn zeroize(&mut self)
