Struct groestlcoin_hashes::sha256t::Hash

pub struct Hash<T: Tag>(/* private fields */);

Output of the SHA256t hash function.

Implementations

impl<T: Tag> Hash<T>

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.

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.

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.
