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 const ZERO: Self

Zero work.

pub fn to_target(self) -> Result<Target, ZeroConversionError>

Converts this Work to Target, target = 2^256 / work - 1.

Errors

If the work is zero.

impl Work

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

Constructs a new Work from a prefixed hex string.

Errors

• If the input string does not contain a 0x (or 0X) prefix.
• If the input string is not a valid hex encoding of a Work.

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

Constructs a new Work from an unprefixed hex string.

Errors

• If the input string contains a 0x (or 0X) prefix.
• If the input string is not a valid hex encoding of a Work.

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

Constructs Work from a big-endian byte array.

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

Constructs 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]
