Expand description

A trait for representing the state of a cryptographic hasher.

Required Methods§

fn seed() -> &'static [u8; 32]

the seed used to initialize hashing Self before the serialization bytes of the actual value

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

Write bytes into the hasher.

fn finish(self) -> HashValue

Finish constructing the HashValue.

Provided Methods§

fn hash_all(bytes: &[u8]) -> HashValue

Convenience method to compute the hash of a complete byte slice.
