Expand description
A hashing engine which bytes can be serialized into.
Required Associated Types§
type MidState
type MidState
Byte array representing the internal state of the hash engine.
Required Associated Constants§
const BLOCK_SIZE: usize
const BLOCK_SIZE: usize
Length of the hash’s internal block size, in bytes.
Required Methods§
fn midstate(&self) -> Self::MidState
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 n_bytes_hashed(&self) -> usize
fn n_bytes_hashed(&self) -> usize
Return the number of bytes already n_bytes_hashed(inputted).
Object Safety§
This trait is not object safe.
