Struct MessageDigest 

pub struct MessageDigest(/* private fields */);

An already-hashed 32-byte message consumed by the WOTS construction.

HashSigsRS does not hash an arbitrary-length application message before signing. The caller is responsible for a domain-separated, collision- resistant application prehash.

Implementations

impl MessageDigest

pub const fn new(bytes: [u8; 32]) -> Self

Wraps a 32-byte application message digest.

pub fn from_slice(bytes: &[u8]) -> Result<Self, LengthError>

Parses a message digest, rejecting every non-32-byte input.

Errors

Returns LengthError unless bytes contains exactly 32 bytes.

pub const fn as_bytes(&self) -> &[u8; 32]

Borrows the digest bytes.

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

Returns the digest bytes.

Trait Implementations

impl Clone for MessageDigest

fn clone(&self) -> MessageDigest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageDigest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for MessageDigest

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MessageDigest

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

Tests for self and other values to be equal, and is used by ==.

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

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