Struct TransparentHasher

Source

pub struct TransparentHasher { /* private fields */ }

Expand description

A trivial implementation of SimpleHasher that simply returns the first 32 bytes of the provided data. This is useful to avoid hashing data when testing, and facilitate debugging specific tree configurations.

Trait Implementations§

Source §

impl SimpleHasher for TransparentHasher

Source §

fn new() -> Self

Creates a new hasher with default state.

Source §

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

Ingests the provided data, updating the hasher’s state.

Source §

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

Consumes the hasher state to produce a digest.

Source §

fn hash(data: impl AsRef<[u8]>) -> [u8; 32]

Returns the digest of the provided data.
