Struct cosmwasm_std::Uint64
source · [−]pub struct Uint64(_);
Expand description
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
sourceimpl Uint64
impl Uint64
pub const MAX: Self
sourcepub const fn new(value: u64) -> Self
pub const fn new(value: u64) -> Self
Creates a Uint64(value).
This method is less flexible than from
but can be called in a const context.
sourcepub const fn to_be_bytes(self) -> [u8; 8]
pub const fn to_be_bytes(self) -> [u8; 8]
Returns a copy of the number as big endian bytes.
sourcepub const fn to_le_bytes(self) -> [u8; 8]
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_sub(self, other: Self) -> Result<Self, OverflowError>
pub fn checked_mul(self, other: Self) -> Result<Self, OverflowError>
pub fn checked_div(self, other: Self) -> Result<Self, DivideByZeroError>
pub fn checked_div_euclid(self, other: Self) -> Result<Self, DivideByZeroError>
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
