Struct u256

pub struct u256 {
    pub lo: u128,
    pub hi: u128,

Fields

lo: u128

hi: u128

Implementations

impl u256

pub fn signed(self) -> i256

Reinterpret as a signed integer

Trait Implementations

impl Add for u256

type Output = u256

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl BitOr for u256

type Output = u256

The resulting type after applying the | operator.

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

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 DInt for u256

type H = u128

Integer that is half the bit width of the integer this trait is implemented for

fn lo(self) -> Self::H

Returns the low half of self

fn hi(self) -> Self::H

Returns the high half of self

fn lo_hi(self) -> (Self::H, Self::H)

Returns the low and high halves of self as a tuple

fn from_lo_hi(lo: Self::H, hi: Self::H) -> Self

Constructs an integer using lower and higher half parts

impl Debug for u256

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

Formats the value using the given formatter.

impl MinInt for u256

const SIGNED: bool = false

If Self is a signed integer

const BITS: u32 = 256u32

The bitwidth of the int type

const ZERO: Self

const ONE: Self

const MIN: Self

const MAX: Self

type OtherSign = i256

Type with the same width but other signedness

type Unsigned = u256

Unsigned version of Self

impl Not for u256

type Output = u256

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for u256

fn eq(&self, other: &u256) -> bool

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

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 u256

fn partial_cmp(&self, other: &u256) -> 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 Shl<u32> for u256

type Output = u256

The resulting type after applying the << operator.

fn shl(self, _rhs: u32) -> Self::Output

Performs the << operation.

impl Shr<u32> for u256

type Output = u256

The resulting type after applying the >> operator.

fn shr(self, rhs: u32) -> Self::Output

Performs the >> operation.

impl Copy for u256

impl StructuralPartialEq for u256
