Struct bitcoin_hashes::sha256d::Hash

pub struct Hash(_);

Trait Implementations

impl Hash for Hash

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 Inner = [u8; 32]

The byte array that represents the hash internally

Important traits for HashEngine

impl Write for HashEngine

fn engine() -> HashEngine

Construct a new engine

fn from_engine(e: HashEngine) -> Hash

Produce a hash from the current state of a given engine

const LEN: usize

Length of the hash, in bytes

fn from_slice(sl: &[u8]) -> Result<Hash, Error>

Copies a byte slice into a hash object

const 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.

fn into_inner(self) -> Self::Inner

Unwraps the hash and returns the underlying byte array

fn as_inner(&self) -> &Self::Inner

Unwraps the hash and returns a reference to the underlying byte array

fn from_inner(inner: Self::Inner) -> Self

Constructs a hash from the underlying byte array

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

Hashes some bytes

impl AsRef<[u8]> for Hash

fn as_ref(&self) -> &[u8]

Performs the conversion.

impl Ord for Hash

fn cmp(&self, other: &Hash) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialOrd<Hash> for Hash

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

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

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Hash) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Hash) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Default for Hash

fn default() -> Hash

Returns the "default value" for a type.

impl Clone for Hash

fn clone(&self) -> Hash

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq<Hash> for Hash

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