Struct Work

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

A 256 bit integer representing work.

Work is a measure of how difficult it is to find a hash below a given Target.

Implementations

impl Work

pub fn to_target(self) -> Target

Converts this Work to Target.

pub fn log2(self) -> f64

Returns log2 of this work.

The result inherently suffers from a loss of precision and is, therefore, meant to be used mainly for informative and displaying purposes, similarly to Bitcoin Core’s log2_work output in its logs.

impl Work

pub fn from_hex(s: &str) -> Result<Work, PrefixedHexError>

Creates Work from a prefixed hex string.

pub fn from_unprefixed_hex(s: &str) -> Result<Work, UnprefixedHexError>

Creates Work from an unprefixed hex string.

pub fn from_be_bytes(bytes: [u8; 32]) -> Work

Creates Work from a big-endian byte array.

pub fn from_le_bytes(bytes: [u8; 32]) -> Work

Creates Work from a little-endian byte array.

pub fn to_be_bytes(self) -> [u8; 32]

Converts Work to a big-endian byte array.

pub fn to_le_bytes(self) -> [u8; 32]

Converts Work to a little-endian byte array.

Trait Implementations

impl Add for Work

type Output = Work

The resulting type after applying the + operator.

fn add(self, rhs: Work) -> Work

Performs the + operation.

impl Clone for Work

fn clone(&self) -> Work

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Work

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

Formats the value using the given formatter.

impl Display for Work

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

Formats the value using the given formatter.

impl Hash for Work

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 LowerHex for Work

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

Formats the value using the given formatter.

impl Ord for Work

fn cmp(&self, other: &Work) -> 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 Work

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

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

const 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 Work

fn partial_cmp(&self, other: &Work) -> 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 Sub for Work

type Output = Work

The resulting type after applying the - operator.

fn sub(self, rhs: Work) -> Work

Performs the - operation.

impl UpperHex for Work

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

Formats the value using the given formatter.
