Struct U256 

pub struct U256(/* private fields */);

A 256-bit unsigned integer.

Implementations

impl U256

pub const MIN: Self

The smallest value that can be represented by this integer type (0).

pub const MAX: Self

The largest value that can be represented by this integer type (2²⁵⁶ − 1).

pub const fn from_byte_array(bytes: [u8; 32]) -> Self

Create a 256-bit unsigned integer from a byte array.

The byte array is in Big Endian order.

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

Convert the integer to a byte array.

The byte array is in Big Endian order.

Trait Implementations

impl AsRef<[u8]> for U256

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

Formats the value using the given formatter.

impl Display for U256

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

Formats the value using the given formatter.

impl From<U256> for UIntValue

fn from(value: U256) -> Self

Converts to this type from the input type.

impl From<u128> for U256

fn from(value: u128) -> Self

Converts to this type from the input type.

impl From<u16> for U256

fn from(value: u16) -> Self

Converts to this type from the input type.

impl From<u32> for U256

fn from(value: u32) -> Self

Converts to this type from the input type.

impl From<u64> for U256

fn from(value: u64) -> Self

Converts to this type from the input type.

impl From<u8> for U256

Converts to this type from the input type.

impl FromStr for U256

type Err = ParseIntError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for U256

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 Ord for U256

fn cmp(&self, other: &U256) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.
