Struct Uint64 

pub struct Uint64(/* private fields */);

A thin wrapper around u64 that is using strings for JSON encoding/decoding, such that the full u64 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 u64 to get the value out:

let a = Uint64::from(42u64);
assert_eq!(a.u64(), 42);

let b = Uint64::from(70u32);
assert_eq!(b.u64(), 70);

Implementations

impl Uint64

pub const fn new(value: u64) -> Self

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

pub const fn zero() -> Self

Creates a Uint64(0)

pub const fn u64(&self) -> u64

Returns a copy of the internal data

pub const fn to_be_bytes(self) -> [u8; 8]

Returns a copy of the number as big endian bytes.

pub const fn to_le_bytes(self) -> [u8; 8]

Returns a copy of the number as little endian bytes.

pub fn is_zero(&self) -> bool

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

pub fn checked_rem(self, other: Self) -> Result<Self, DivideByZeroError>

pub fn wrapping_add(self, other: Self) -> Self

pub fn wrapping_sub(self, other: Self) -> Self

pub fn wrapping_mul(self, other: Self) -> Self

pub fn wrapping_pow(self, other: u32) -> Self

impl Uint64

pub fn multiply_ratio<A: Into<u64>, B: Into<u64>>( &self, numerator: A, denominator: B, ) -> Uint64

Returns self * numerator / denominator

pub fn full_mul(self, rhs: impl Into<u64>) -> Uint128

Multiplies two Uint64/u64 values without overflow, producing an Uint128.

Examples

use prov_cosmwasm_std::Uint64;

let a = Uint64::MAX;
let result = a.full_mul(2u32);
assert_eq!(result.to_string(), "36893488147419103230");
