Struct U256 

pub struct U256 {
    left: u128,
    right: u128,
}

Duct tape two u128 together to make a 256 bit wide integer.

Fields

left: u128

right: u128

Implementations

impl U256

fn bit_set(&mut self, offset: usize)

fn non_zero(self) -> bool

fn left_roll(self, width: usize) -> Self

Perform a rotate_left where the width can be different from 256 bits.

fn right_roll(self, width: usize) -> Self

Perform a rotate_right where the width can be different from 256 bits.

Trait Implementations

impl BitAnd for U256

Implement operator bitwise logic so that we can use the regular &, | and ! notation.

type Output = U256

The resulting type after applying the & operator.

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

Performs the & operation.

impl BitOr for U256

type Output = U256

The resulting type after applying the | operator.

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

Performs the | operation.

impl Clone for U256

fn clone(&self) -> U256

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for U256

fn default() -> U256

Returns the “default value” for a type.

impl Not for U256

type Output = U256

The resulting type after applying the ! operator.

fn not(self) -> Self

Performs the unary ! operation.

impl Copy for U256
