Struct Price

pub struct Price { /* private fields */ }

Price in fractional representation.

Implementations

impl Price

pub fn new(numerator: i32, denominator: i32) -> Price

Create from numerator and denominator.

pub fn numerator(&self) -> i32

Return the price numerator.

pub fn denominator(&self) -> i32

Return the price denominator.

Trait Implementations

impl Clone for Price

fn clone(&self) -> Price

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Price

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Price

fn deserialize<D>(deserializer: D) -> Result<Price, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for Price

fn cmp(&self, other: &Price) -> 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 Price

fn eq(&self, other: &Price) -> 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 Price

fn partial_cmp(&self, other: &Price) -> 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 Serialize for Price

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

where S: Serializer,

Serialize this value into the given Serde serializer.
