[][src]Trait bitcoin_hashes::HashEngine

pub trait HashEngine: Clone + Default {
    type MidState;

    const BLOCK_SIZE: usize;

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

A hashing engine which bytes can be serialized into. It is expected to implement the io::Write trait, but to never return errors under any conditions.

Associated Types

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
