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)
