Implementations

impl Hash

pub fn forward_hex(&self) -> impl LowerHex + UpperHex

Displays hex forwards, regardless of how this type would display it naturally.

This is mainly intended as an internal method and you shouldn’t need it unless you’re doing something special.

pub fn backward_hex(&self) -> impl LowerHex + UpperHex

Displays hex backwards, regardless of how this type would display it naturally.

This is mainly intended as an internal method and you shouldn’t need it unless you’re doing something special.

The byte array that represents the hash internally.

const LEN: usize = 20usize

Length of the hash, in bytes.

const DISPLAY_BACKWARD: bool = false

fn from_engine(e: HashEngine) -> Hash

Produces a hash from the current state of a given engine.

impl Ord for Hash

fn cmp(&self, other: &Hash) -> Ordering

Restrict a value to a certain interval.

impl PartialEq<Hash> for Hash

fn eq(&self, other: &Hash) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
