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.

impl Hash

pub fn hash_again(&self) -> Hash

Iterate the sha256 algorithm to turn a sha256 hash into a sha256d hash

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.
