Struct bdk_chain::bitcoin::pow::Work

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

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.
