Struct Money

#[repr(C)]
pub struct Money {
    pub raw: MoneyRaw,
    pub currency: Currency,
}

Represents an amount of money in a specified currency denomination.

• MONEY_MAX = {MONEY_MAX}
• MONEY_MIN = {MONEY_MIN}

Fields

raw: MoneyRaw

Represents the raw fixed-point amount, with currency.precision defining the number of decimal places.

currency: Currency

The currency denomination associated with the monetary amount.

Implementations

impl Money

pub fn new_checked(amount: f64, currency: Currency) -> Result<Self>

Creates a new Money instance with correctness checking.

Errors

Returns an error if amount is invalid outside the representable range [{MONEY_MIN}, {MONEY_MAX}].

Notes

PyO3 requires a Result type for proper error handling and stacktrace printing in Python.

Panics

Panics if a correctness check fails. See Money::new_checked for more details.

pub fn from_raw(raw: MoneyRaw, currency: Currency) -> Self

Creates a new Money instance from the given raw fixed-point value and the specified currency.

pub fn zero(currency: Currency) -> Self

Creates a new Money instance with a value of zero with the given Currency.

Panics

Panics if a correctness check fails. See Money::new_checked for more details.

pub fn is_zero(&self) -> bool

Returns true if the value of this instance is zero.

pub fn as_f64(&self) -> f64

pub fn as_decimal(&self) -> Decimal

Returns the value of this instance as a Decimal.
