Struct blake2s_simd::blake2sp::State

pub struct State { /* fields omitted */ }

An incremental hasher for BLAKE2sp, just like the State type for BLAKE2s.

Example

use blake2s_simd::blake2sp;

let mut state = blake2sp::State::new();
state.update(b"foo");
state.update(b"bar");
let hash = state.finalize();

let expected = "268120e51df583c61d6bfb7915f1c8ead299696c42f413092cd0b2247e1a388d";
assert_eq!(expected, &hash.to_hex());

Implementations

impl State

pub fn new() -> Self

Equivalent to State::default() or Params::default().to_state().

pub fn update(&mut self, input: &[u8]) -> &mut Self

Add input to the hash. You can call update any number of times.

pub fn finalize(&self) -> Hash

Finalize the state and return a Hash. This method is idempotent, and calling it multiple times will give the same result. It’s also possible to update with more input in between.

pub fn count(&self) -> u64

Return the total number of bytes input so far.

Note that count doesn’t include the bytes of the key block, if any. It’s exactly the total number of input bytes fed to update.

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for State

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

Formats the value using the given formatter.

impl Default for State

fn default() -> Self

Returns the “default value” for a type.
