Struct Money 

pub struct Money { /* private fields */ }

An amount in a currency, counted in the currency’s smallest unit: {"currency": "EUR", "base_units": "-1240"} is −12.40 euros.

The count is exact and has one written form only – an integer as a string ("-1240"), never a JSON number – so the same amount always has the same bytes and the same hash. Its magnitude is at most Money::MAX_BASE_UNITS. Reading, checking and summing amounts never needs the currency’s definition.

Implementations

impl Money

pub const MAX_BASE_UNITS: i128

The largest magnitude of an amount in base units: 10^38 − 1. Every implementation can represent it.

pub fn new(base_units: i128, currency: Currency) -> Option<Self>

base_units of the currency’s smallest unit; None if the magnitude is above Self::MAX_BASE_UNITS.

pub fn currency(&self) -> &Currency

The currency.

pub fn base_units(&self) -> i128

The amount in the currency’s smallest unit; its sign is given by its use (see crate::Posting).

Trait Implementations

impl Clone for Money

fn clone(&self) -> Money

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Money

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Money

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Money

impl Eq for Money

impl Hash for Money

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 Money

fn neg(self) -> Money

The same amount with the opposite sign; the range is symmetric, so this cannot overflow.

type Output = Money

impl Object for Money

const TYPE: &'static str = "money"

The type, written as "type" when the object stands on its own.

impl PartialEq for Money

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Money

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
