Struct I256

pub struct I256 { /* private fields */ }

I256 holds a 256-bit signed integer.

Examples

use soroban_sdk::{I256, Env};

let env = Env::default();

let i1 = I256::from_i32(&env, -6);
let i2 = I256::from_i32(&env, 3);
assert_eq!(i1.add(&i2), I256::from_i32(&env, -3));

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for I256

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

Formats the value using the given formatter.

impl From<&I256> for I256

fn from(v: &I256) -> Self

Converts to this type from the input type.

impl From<&I256> for I256Val

fn from(v: &I256) -> Self

Converts to this type from the input type.

impl From<&I256> for ScVal

fn from(v: &I256) -> Self

Converts to this type from the input type.

impl From<I256> for I256Val

fn from(v: I256) -> Self

impl Ord for I256

fn cmp(&self, other: &Self) -> 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 I256

fn eq(&self, other: &Self) -> 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 I256

fn partial_cmp(&self, other: &Self) -> 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.
