Trait which applies to hashes of all types

Associated Types

type Engine: HashEngine

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

type Inner: FromHex

The byte array that represents the hash internally

Associated Constants

const LEN: usize

Length of the hash, in bytes

const DISPLAY_BACKWARD: bool

Flag indicating whether user-visible serializations of this hash should be backward. For some reason Satoshi decided this should be true for Sha256dHash, so here we are.

Required methods

fn from_engine(e: Self::Engine) -> Self

Produce a hash from the current state of a given engine

fn from_slice(sl: &[u8]) -> Result<Self, Error>

Copies a byte slice into a hash object

fn into_inner(self) -> Self::Inner

Unwraps the hash and returns the underlying byte array

fn as_inner(&self) -> &Self::Inner

Unwraps the hash and returns a reference to the underlying byte array

fn from_inner(inner: Self::Inner) -> Self

Constructs a hash from the underlying byte array

Provided methods

fn engine() -> Self::Engine

Construct a new engine

fn hash(data: &[u8]) -> Self

Hashes some bytes
