Struct LogosMoney 

pub struct LogosMoney(pub Money);

Money for the compiled tier — an exact amount in a currency, mirroring base::Money. + − require the SAME currency (a runtime-panic backstop; the type checker rejects mismatches first), × ÷ scale by an exact number, and a same-currency ÷ is the dimensionless ratio.

Implementations

impl LogosMoney

pub fn of(amount: LogosDecimal, code: &str) -> Self

Money of a Decimal amount in the named currency. Panics on an unknown currency, which the front-end has already rejected before codegen.

pub fn from_i64(amount: i64, code: &str) -> Self

Money of an integer amount — the 5 USD case (codegen passes the literal directly).

pub fn add(&self, other: &LogosMoney) -> LogosMoney

pub fn sub(&self, other: &LogosMoney) -> LogosMoney

pub fn scale_int(&self, k: i64) -> LogosMoney

Scale by an integer (19.99 USD × 3), re-quantised to the currency.

pub fn scale_decimal(&self, k: &LogosDecimal) -> LogosMoney

Scale by an exact decimal (price × 1.5), re-quantised to the currency.

pub fn div_int(&self, k: i64) -> LogosMoney

Divide by an integer (split a bill), re-quantised to the currency.

pub fn ratio(&self, other: &LogosMoney) -> LogosRational

The exact dimensionless ratio of two same-currency amounts.

Trait Implementations

impl Clone for LogosMoney

fn clone(&self) -> LogosMoney

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogosMoney

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

Formats the value using the given formatter.

impl Display for LogosMoney

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

Formats the value using the given formatter.

impl PartialEq for LogosMoney

fn eq(&self, other: &Self) -> 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 LogosMoney

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

Ordered by amount within a currency; across currencies it is incomparable (None).

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.
