impl Default for Decimal256

pub fn default() -> Decimal256

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for Decimal256

Deserializes as a base64 string

pub fn deserialize<D>(deserializer: D) -> Result<Decimal256, D::Error> where
    D: Deserializer<'de>,

impl Div<Decimal256> for Decimal256

type Output = Self

The resulting type after applying the / operator.

pub fn div(self, rhs: Self) -> Self

Performs the / operation.

impl Div<Decimal256> for Uint256

type Output = Self

The resulting type after applying the / operator.

impl Eq for Decimal256

impl From<Decimal> for Decimal256

pub fn from(val: Decimal) -> Self

Performs the conversion.

impl FromStr for Decimal256

type Err = StdError

The associated error which can be returned from parsing.

pub fn from_str(input: &str) -> Result<Self, Self::Err>

Converts the decimal string to a Decimal256 Possible inputs: "1.23", "1", "000012", "1.123000000" Disallowed: "", ".23"

This never performs any kind of rounding. More than 18 fractional digits, even zeros, result in an error.

impl Mul<Decimal256> for Uint256

Both du and ud with d: Decimal256 and u: Uint256 returns an Uint256. There is no specific reason for this decision other than the initial use cases we have. If you need a Decimal256 result for the same calculation, use Decimal256(du) or Decimal256(ud).

type Output = Self

The resulting type after applying the * operator.

pub fn mul(self, rhs: Decimal256) -> Self::Output

Performs the * operation.

impl Mul<Uint256> for Decimal256
