Struct cosmwasm_std::Uint128

pub struct Uint128(/* private fields */);

A thin wrapper around u128 that is using strings for JSON encoding/decoding, such that the full u128 range can be used for clients that convert JSON numbers to floats, like JavaScript and jq.

Examples

Use from to create instances of this and u128 to get the value out:

let a = Uint128::from(123u128);
assert_eq!(a.u128(), 123);

let b = Uint128::from(42u64);
assert_eq!(b.u128(), 42);

let c = Uint128::from(70u32);
assert_eq!(c.u128(), 70);

Implementations

impl Uint128

pub const MAX: Self = _

pub const MIN: Self = _

pub const fn new(value: u128) -> Self

Creates a Uint128(value).

This method is less flexible than from but can be called in a const context.

pub const fn zero() -> Self

Creates a Uint128(0)

pub const fn one() -> Self

Creates a Uint128(1)

pub const fn u128(&self) -> u128

Returns a copy of the internal data

pub const fn to_be_bytes(self) -> [u8; 16]

Returns a copy of the number as big endian bytes.

pub const fn to_le_bytes(self) -> [u8; 16]

Returns a copy of the number as little endian bytes.

pub const fn is_zero(&self) -> bool

pub const fn pow(self, exp: u32) -> Self

pub fn multiply_ratio<A: Into<u128>, B: Into<u128>>( &self, numerator: A, denominator: B ) -> Uint128

Returns self * numerator / denominator.

Due to the nature of the integer division involved, the result is always floored. E.g. 5 * 99/100 = 4.

pub fn checked_multiply_ratio<A: Into<u128>, B: Into<u128>>( &self, numerator: A, denominator: B ) -> Result<Uint128, CheckedMultiplyRatioError>

Returns self * numerator / denominator.

Due to the nature of the integer division involved, the result is always floored. E.g. 5 * 99/100 = 4.

pub fn full_mul(self, rhs: impl Into<Self>) -> Uint256

Multiplies two u128 values without overflow, producing an Uint256.

Examples

use cosmwasm_std::Uint128;

let a = Uint128::MAX;
let result = a.full_mul(2u32);
assert_eq!(result.to_string(), "680564733841876926926749214863536422910");

pub fn checked_add(self, other: Self) -> Result<Self, OverflowError>

pub fn saturating_pow(self, exp: u32) -> Self

pub const fn strict_add(self, rhs: Self) -> Self

This is the same as Uint128::add but const.

pub const fn strict_sub(self, other: Self) -> Self

Strict integer subtraction. Computes self - rhs, panicking if overflow occurred.

This is the same as Uint128::sub but const.
