Struct Blake3Hasher 

pub struct Blake3Hasher { /* private fields */ }

Available on (crate features hash-blake3 or hash-sha2) and crate feature hash-blake3 only.

Streaming BLAKE3 hasher for inputs that don’t fit in memory or arrive in chunks.

Construct with Blake3Hasher::new, feed data with update, and finalise with finalize (returns the default 32-byte digest) or finalize_xof (returns an arbitrary-length digest).

update can be called any number of times; the hasher is consumed by finalisation.

Example

use crypt_io::hash::Blake3Hasher;

let mut h = Blake3Hasher::new();
h.update(b"first ");
h.update(b"second");
let d = h.finalize();
assert_eq!(d.len(), 32);

Implementations

impl Blake3Hasher

pub fn new() -> Self

Construct a fresh hasher.

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

Absorb data into the running hash. Returns &mut Self so calls can chain.

pub fn finalize(self) -> [u8; 32]

Finalise the hash and return a 32-byte digest. Consumes the hasher.

pub fn finalize_xof(self, len: usize) -> Vec<u8>

Finalise the hash and return len bytes of XOF output. Consumes the hasher.
