Struct Decimal

#[repr(C)]
pub struct Decimal { /* private fields */ }

A fixed-point decimal number. Holds exactly 19 digits after the decimal point and a 64-bit value before the decimal point.

Implementations

impl Decimal

pub const FRACTIONAL_PART_DENOMINATOR: u64 = 10_000_000_000_000_000_000u64

pub const MIN: Self

pub const MAX: Self

pub const fn new(integer: i64, fractional: u64) -> Self

pub fn integer_part(&self) -> i64

Get the integer part of the decimal as normal signed 64 bit number

pub fn fractional_part(&self) -> u64

Get the fractional part of the decimal, in multiples of 10^-19 (Decimal::FRACTIONAL_PART_DENOMINATOR) This means, the smallest decimal representable is 10^-19, and up to 19 decimal places are supported.

Trait Implementations

impl Add for Decimal

type Output = Decimal

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for Decimal

fn clone(&self) -> Decimal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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 Display for Decimal

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

Formats the value using the given formatter.

impl Hash for Decimal

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Neg for Decimal

type Output = Decimal

The resulting type after applying the - operator.

fn neg(self) -> Self::Output

Performs the unary - operation.

impl Ord for Decimal

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Decimal

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd 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: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Sub for Decimal

type Output = Decimal

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.
