Struct ChaCha

pub struct ChaCha { /* private fields */ }

Parameters of a ChaCha stream, including fixed parameters and current position.

Implementations

impl ChaCha

pub fn new(key: &[u8; 32], nonce: &[u8]) -> Self

pub fn refill4(&mut self, drounds: u32, out: &mut [u8; 256])

Produce 4 blocks of output, advancing the state

pub fn refill(&mut self, drounds: u32, out: &mut [u8; 64])

Produce a block of output, advancing the state

pub fn set_stream_param(&mut self, param: u32, value: u64)

pub fn get_stream_param(&self, param: u32) -> u64

pub fn stream32_eq(&self, rhs: &Self) -> bool

Return whether rhs represents the same stream, irrespective of current 32-bit position.

pub fn stream64_eq(&self, rhs: &Self) -> bool

Return whether rhs represents the same stream, irrespective of current 64-bit position.

Trait Implementations

impl Clone for ChaCha

fn clone(&self) -> ChaCha

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for ChaCha

fn eq(&self, other: &ChaCha) -> 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.
