The resulting type after applying the + operator.

fn add(self, rhs: Self) -> StdResult<Self>

Performs the + operation.

impl Canonize for Decimal256

type Output = Decimal256

fn canonize(self, _api: &impl Api) -> StdResult<Self::Output>

impl Clone for Decimal256

fn clone(&self) -> Decimal256

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Decimal256

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Decimal256

fn default() -> Decimal256

Returns the “default value” for a type.

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

Deserializes as a base64 string

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

Deserialize this value from the given Serde deserializer.

impl Display for Decimal256

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Div<Decimal256> for Decimal256

type Output = Result<Decimal256, StdError>

The resulting type after applying the / operator.

fn div(self, rhs: Self) -> StdResult<Self>

Performs the / operation.

impl From<Decimal256> for Uint256

fn from(value: Decimal256) -> Self

Converts to this type from the input type.

impl FromStr for Decimal256

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