Struct cosmwasm_std::Int64

pub struct Int64(/* private fields */);

An implementation of i64 that is using strings for JSON encoding/decoding, such that the full i64 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 i64 to get the value out:

let a = Int64::from(258i64);
assert_eq!(a.i64(), 258);

Implementations

impl Int64

pub const MAX: Int64 = _

pub const MIN: Int64 = _

pub const fn new(value: i64) -> Self

Creates a Int64(value).

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

pub const fn zero() -> Self

Creates a Int64(0)

pub const fn one() -> Self

Creates a Int64(1)

pub const fn i64(&self) -> i64

Returns a copy of the internal data

pub const fn from_be_bytes(data: [u8; 8]) -> Self

pub const fn from_le_bytes(data: [u8; 8]) -> Self

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 const fn is_zero(&self) -> bool

pub const fn is_negative(&self) -> bool

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

pub fn checked_multiply_ratio<A: Into<Self>, B: Into<Self>>( &self, numerator: A, denominator: B ) -> Result<Self, 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>) -> Int128

Multiplies two Int64 values without overflow, producing an Int128.

Examples

use cosmwasm_std::Int64;

let a = Int64::MAX;
let result = a.full_mul(2i32);
assert_eq!(result.to_string(), "18446744073709551614");

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_pow(self, exp: u32) -> Result<Self, OverflowError>

pub fn checked_div(self, other: Self) -> Result<Self, DivisionError>

pub fn checked_div_euclid(self, other: Self) -> Result<Self, DivisionError>

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

pub fn checked_shr(self, other: u32) -> Result<Self, OverflowError>

pub fn checked_shl(self, other: u32) -> Result<Self, OverflowError>

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

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

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

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

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

pub const fn abs_diff(self, other: Self) -> Uint64

pub const fn abs(self) -> Self

pub const fn unsigned_abs(self) -> Uint64

pub const fn strict_neg(self) -> Self

Strict negation. Computes -self, panicking if self == MIN.

This is the same as Int64::neg but const.
