Tuple Fields

0: [u8; 32]

Implementations

impl Midstate

pub const fn from_byte_array(inner: [u8; 32]) -> Midstate

Construct a new Midstate from the inner value.

pub fn from_slice(sl: &[u8]) -> Result<Midstate, FromSliceError>

Copies a byte slice into the Midstate object.

pub fn to_byte_array(self) -> [u8; 32]

Unwraps the Midstate and returns the underlying byte array.

pub const fn hash_tag(tag: &[u8]) -> Midstate

Creates midstate for tagged hashes.

Warning: this function is inefficient. It should be only used in const context.

Computes non-finalized hash of sha256(tag) || sha256(tag) for use in sha256t. It’s provided for use with sha256t.
