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: 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 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) -> Self::Bytes

Returns the underlying byte array.

fn as_byte_array(&self) -> &Self::Bytes

Returns a reference to the underlying byte array.

fn from_byte_array(bytes: T::Bytes) -> Self

Constructs a hash from the underlying byte array.

fn all_zeros() -> Self

Returns an all zero hash.

fn engine() -> Self::Engine

Constructs a new engine.

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

Hashes some bytes.

const DISPLAY_BACKWARD: bool = false

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.

impl<T: Hash + Hash> Hash for Hmac<T>

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,

fn index(&self, index: RangeFull) -> &[u8]

Performs the indexing (container[index]) operation.

impl<T: Hash> Index<RangeTo<usize>> for Hmac<T>

type Output = [u8]

The returned type after indexing.

fn index(&self, index: RangeTo<usize>) -> &[u8]

Performs the indexing (container[index]) operation.

impl<T: Hash> Index<usize> for Hmac<T>

type Output = u8

The returned type after indexing.

fn index(&self, index: usize) -> &u8

Performs the indexing (container[index]) operation.

impl<T: Hash + JsonSchema> JsonSchema for Hmac<T>

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

impl<T: Hash> LowerHex for Hmac<T>

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

Formats the value using the given formatter.

impl<T: Ord + Hash> Ord for Hmac<T>

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

fn eq(&self, other: &Hmac<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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