Implementations§

source§

impl Hash

source

pub fn from_bytes_ref(bytes: &[u8; 32]) -> &Self

Zero cost conversion between a fixed length byte array shared reference and a shared reference to this Hash type.

source

pub fn from_bytes_mut(bytes: &mut [u8; 32]) -> &mut Self

Zero cost conversion between a fixed length byte array exclusive reference and an exclusive reference to this Hash type.

source§

impl Hash

source

pub fn hash_again(&self) -> Hash

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

source

pub const fn const_hash(bytes: &[u8]) -> Self
