Struct Hash 

pub struct Hash<T: Tag>(/* private fields */);

Output of the SHA256t hash function.

Implementations

impl<T: Tag> Hash<T>

pub fn forward_hex(&self) -> impl '_ + LowerHex + UpperHex

Displays hex forwards, regardless of how this type would display it naturally.

This is mainly intended as an internal method and you shouldn’t need it unless you’re doing something special.

pub fn backward_hex(&self) -> impl '_ + LowerHex + UpperHex

Displays hex backwards, regardless of how this type would display it naturally.

This is mainly intended as an internal method and you shouldn’t need it unless you’re doing something special.

pub fn from_bytes_ref(bytes: &[u8; 32]) -> &Self

Zero cost conversion between a fixed length byte array shared reference and a shared reference to this Hash type.

pub fn from_bytes_mut(bytes: &mut [u8; 32]) -> &mut Self

Zero cost conversion between a fixed length byte array exclusive reference and an exclusive reference to this Hash type.

Trait Implementations

fn default() -> Self

Returns the “default value” for a type.

impl<T: Tag> FromStr for Hash<T>

type Err = HexToArrayError

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: Tag> Hash for Hash<T>

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl<T: Tag> Hash for Hash<T>

const LEN: usize = 32usize

Length of the hash, in bytes.

const DISPLAY_BACKWARD: bool = true

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.

type Engine = HashEngine

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 = [u8; 32]

The byte array that represents the hash internally.

fn engine() -> Self::Engine

Constructs a new engine.

fn from_engine(e: HashEngine) -> Hash<T>

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

fn from_slice(sl: &[u8]) -> Result<Hash<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: Self::Bytes) -> Self

Constructs a hash from the underlying byte array.

fn all_zeros() -> Self

Returns an all zero hash.

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

Hashes some bytes.

impl<I: SliceIndex<[u8]>, T: Tag> Index<I> for Hash<T>

type Output = <I as SliceIndex<[u8]>>::Output

The returned type after indexing.

fn index(&self, index: I) -> &Self::Output

Performs the indexing (container[index]) operation.

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

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

Formats the value using the given formatter.

impl<T: Tag> Ord for Hash<T>

fn cmp(&self, other: &Hash<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 min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: Tag> PartialEq for Hash<T>

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<T: Tag> PartialOrd for Hash<T>

fn partial_cmp(&self, other: &Hash<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.
