Struct Hash

pub struct Hash(/* private fields */);

A hash to uniquely (or close enough) identify one of the main blockchain constructs. Used pervasively for blocks, transactions and outputs.

Implementations

impl Hash

pub const LEN: usize = 32usize

A hash is 32 bytes.

pub fn from_vec(v: &[u8]) -> Hash

Builds a Hash from a byte vector. If the vector is too short, it will be completed by zeroes. If it’s too long, it will be truncated.

pub fn to_vec(&self) -> Vec<u8>

Converts the hash to a byte vector

pub fn as_bytes(&self) -> &[u8]

Returns a byte slice of the hash contents.

pub fn from_hex(hex: &str) -> Result<Hash, Error>

Convert hex string back to hash.

pub fn to_u64(&self) -> u64

Most significant 64 bits

Trait Implementations

impl AsRef<[u8]> for Hash

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

Converts this type into a shared reference of the (usually inferred) input 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 Debug for Hash

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

Formats the value using the given formatter.

impl Default for Hash

fn default() -> Hash

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Hash

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Hash

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

Formats the value using the given formatter.

impl Hash for Hash

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,

Feeds a slice of this type into the given Hasher.

impl Index<Range<usize>> for Hash

type Output = [u8]

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl Index<RangeFrom<usize>> for Hash

type Output = [u8]

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl Index<RangeFull> for Hash

type Output = [u8]

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl Index<RangeTo<usize>> for Hash

type Output = [u8]

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl Index<usize> for Hash

type Output = u8

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

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

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 PartialEq for Hash

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

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

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Hash

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
