impl<T> FromStr for Hmac<T>where T: Hash + FromStr,

type Err = <T as FromStr>::Err

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Hmac<T>, <Hmac<T> as FromStr>::Err>

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>, Error>

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.

Returns an all zero hash.

fn engine() -> Self::Engine

Constructs a new engine.

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

Hashes some bytes.

fn cmp(&self, other: &Hmac<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.
