Trait bitcoin_hashes::HashEngine

pub trait HashEngine: Clone + Default {
    type MidState;

    const BLOCK_SIZE: usize;

    // Required methods
    fn midstate(&self) -> Self::MidState;
    fn input(&mut self, data: &[u8]);
    fn n_bytes_hashed(&self) -> usize;
}

A hashing engine which bytes can be serialized into.

Required Associated Types

type MidState

Byte array representing the internal state of the hash engine.

Required Associated Constants

const BLOCK_SIZE: usize

Length of the hash’s internal block size, in bytes.

Required Methods

fn midstate(&self) -> Self::MidState

Outputs the midstate of the hash engine. This function should not be used directly unless you really know what you’re doing.

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

Add data to the hash engine.

fn n_bytes_hashed(&self) -> usize

Return the number of bytes already n_bytes_hashed(inputted).

Object Safety

This trait is not object safe.
