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

impl<T> Hash for Hmac<T>

where T: Hash,

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 Bytes = <T as Hash>::Bytes

The byte array that represents the hash internally.

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

Produces a hash from the current state of a given engine.

const LEN: usize = T::LEN

Length of the hash, in bytes.

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

Copies a byte slice into a hash object.

fn to_byte_array(self) -> <Hmac<T> as Hash>::Bytes

Returns the underlying byte array.

fn as_byte_array(&self) -> &<Hmac<T> as Hash>::Bytes

Returns a reference to the underlying byte array.

fn from_byte_array(bytes: <T as Hash>::Bytes) -> Hmac<T>

Constructs a hash from the underlying byte array.

fn all_zeros() -> Hmac<T>

Returns an all zero hash.

fn engine() -> Self::Engine

Constructs a new engine.

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

Hashes some bytes.

fn hash_byte_chunks<B, I>(byte_slices: I) -> Self

where B: AsRef<[u8]>, I: IntoIterator<Item = B>,

Hashes all the byte slices retrieved from the iterator together.

const DISPLAY_BACKWARD: bool = false
