Struct Blake2s 

pub struct Blake2s { /* private fields */ }

BLAKE2s hasher (RFC 7693). Default: 32-byte output, 64-byte blocks.

32-bit oriented sibling of BLAKE2b; faster on Cortex-M and 32-bit RISC-V targets.

Implementations

impl Blake2s

pub fn with_output_len(out_len: usize) -> Blake2s

Create a BLAKE2s hasher with a custom output length (1..=32 bytes).

Trait Implementations

impl Clone for Blake2s

fn clone(&self) -> Blake2s

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Digest for Blake2s

const OUTPUT_LEN: usize = 32

The digest length in octets.

const BLOCK_LEN: usize = 64

The internal block size in octets — the rate for the Merkle–Damgård / sponge construction. Needed by keyed constructions such as HMAC.

fn new() -> Blake2s

Create a fresh hasher.

fn update(&mut self, data: &[u8])

Absorb a chunk of input. May be called repeatedly.

fn finalize(self, out: &mut [u8])

Consume the hasher and write the digest into out.

fn digest(data: &[u8], out: &mut [u8])

One-shot convenience: update(data) then finalize(out).
