Struct bitcoin::pow::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 const MAINNET_MIN: Work = _

Lowest possible work value for Mainnet. See comment on Params::pow_limit for more info.

pub const TESTNET_MIN: Work = _

Lowest possible work value for Testnet. See comment on Params::pow_limit for more info.

pub const SIGNET_MIN: Work = _

Lowest possible work value for Signet. See comment on Params::pow_limit for more info.

pub const REGTEST_MIN: Work = _

Lowest possible work value for Regtest. See comment on Params::pow_limit for more info.

pub fn to_target(self) -> Target

Converts this Work to Target.

pub fn log2(self) -> f64

Available on crate feature std only.

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_be_bytes(bytes: [u8; 32]) -> Work

Creates Self from a big-endian byte array.

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

Creates Self from a little-endian byte array.

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

Converts self to a big-endian byte array.

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

Converts self 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: Self) -> Self

Performs the + operation.

impl Clone for Work

fn clone(&self) -> Work

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Work

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Work

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Work

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

Formats the value using the given formatter.

impl Hash for Work

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 LowerHex for Work

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

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) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Work

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

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

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

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

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

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

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

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

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

impl Serialize for Work

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

Serialize this value into the given Serde serializer.

impl Sub for Work

type Output = Work

The resulting type after applying the - operator.

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

Performs the - operation.

impl UpperHex for Work

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

Formats the value using the given formatter.
