Returns a copy of the value.

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

impl<T: HashTrait> Debug for Hmac<T>

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

Formats the value using the given formatter.

impl<T: Default + HashTrait> Default for Hmac<T>

fn default() -> Hmac<T>

Returns the “default value” for a type.

impl<'de, T: HashTrait + Deserialize<'de>> Deserialize<'de> for Hmac<T>

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Hmac<T>, D::Error>

Deserialize this value from the given Serde deserializer.

impl<T: HashTrait> Display for Hmac<T>

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

Formats the value using the given formatter.

impl<T: HashTrait + FromStr> FromStr for Hmac<T>

type Err = <T as FromStr>::Err

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl<T: HashTrait> Hash for Hmac<T>

type Engine = HmacEngine<T>

A hashing engine which bytes can be serialized into. It is expected to implement the io::Write trait, and to never return errors under any conditions.

type Inner = T::Inner

The byte array that represents the hash internally

fn from_engine(e: HmacEngine<T>) -> Hmac<T>

Produce a hash from the current state of a given engine

const LEN: usize

Length of the hash, in bytes

fn from_slice(sl: &[u8]) -> Result<Hmac<T>, Error>

Copies a byte slice into a hash object

fn into_inner(self) -> Self::Inner

Unwraps the hash and returns the underlying byte array

fn as_inner(&self) -> &Self::Inner

Unwraps the hash and returns a reference to the underlying byte array

fn from_inner(inner: T::Inner) -> Self

Constructs a hash from the underlying byte array

fn engine() -> Self::Engine

Construct a new engine

fn hash(data: &[u8]) -> Self

Hashes some bytes

const DISPLAY_BACKWARD: bool

Flag indicating whether user-visible serializations of this hash should be backward. For some reason Satoshi decided this should be true for Sha256dHash, so here we are.
