Struct bitcoin_hashes::hmac::Hmac

pub struct Hmac<T: Hash>(_);

A hash computed from a RFC 2104 HMAC. Parameterized by the underlying hash function.

Trait Implementations

impl<T: Hash> 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

Important traits for HmacEngine<T>

impl<T: Hash> Write for HmacEngine<T>

fn engine() -> HmacEngine<T>

Construct a new engine

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

Produce a hash from the current state of a given engine

fn 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 block_size() -> usize

Length of the hash's internal block size, in bytes

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

Hashes some bytes

fn 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.
