Struct cosmwasm_std::Decimal

pub struct Decimal(_);

A fixed-point decimal value with 18 fractional digits, i.e. Decimal(1_000_000_000_000_000_000) == 1.0

The greatest possible value that can be represented is 340282366920938463463.374607431768211455 (which is (2^128 - 1) / 10^18)

Implementations

impl Decimal

pub const MAX: Decimal

pub const fn one() -> Decimal

Create a 1.0 Decimal

pub const fn zero() -> Decimal

Create a 0.0 Decimal

pub fn percent(x: u64) -> Decimal

Convert x% into Decimal

pub fn permille(x: u64) -> Decimal

Convert permille (x/1000) into Decimal

pub fn from_ratio<A: Into<u128>, B: Into<u128>>(
    nominator: A,
    denominator: B
) -> Decimal

pub fn is_zero(&self) -> bool

Trait Implementations

impl Add<Decimal> for Decimal

type Output = Self

The resulting type after applying the + operator.

fn add(self, other: Self) -> Self

Performs the + operation.

impl Clone for Decimal

fn clone(&self) -> Decimal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Decimal

impl Debug for Decimal

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

Formats the value using the given formatter.

impl Default for Decimal

fn default() -> Decimal

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for Decimal

Deserializes as a base64 string

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

Deserialize this value from the given Serde deserializer.

impl Display for Decimal

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

Formats the value using the given formatter.

impl Eq for Decimal

impl FromStr for Decimal

type Err = StdError

The associated error which can be returned from parsing.

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

Converts the decimal string to a Decimal 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 JsonSchema for Decimal

fn schema_name() -> String

The name of the generated JSON Schema.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Mul<Decimal> for Uint128

Both du and ud with d: Decimal and u: Uint128 returns an Uint128. There is no specific reason for this decision other than the initial use cases we have. If you need a Decimal result for the same calculation, use Decimal(du) or Decimal(ud).

type Output = Self

The resulting type after applying the * operator.

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

Performs the * operation.

impl Mul<Uint128> for Decimal

type Output = Uint128

The resulting type after applying the * operator.

fn mul(self, rhs: Uint128) -> Self::Output

Performs the * operation.

impl Ord for Decimal

fn cmp(&self, other: &Decimal) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Decimal> for Decimal

fn eq(&self, other: &Decimal) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Decimal) -> bool

This method tests for !=.

impl PartialOrd<Decimal> for Decimal

fn partial_cmp(&self, other: &Decimal) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Decimal) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Decimal) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Decimal) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Decimal) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Decimal

Serializes as a decimal string

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.
