Struct LogosDecimal 

pub struct LogosDecimal(pub Decimal);

An exact base-10 fixed-point number — money’s runtime type on the compiled-to-Rust path, the AOT mirror of the interpreter’s Decimal. decimal("19.99") compiles to LogosDecimal::parse("19.99"); + − × stay exact Decimal (scale preserved), and ÷ widens to the exact LogosRational (base-10 division need not terminate). Display shows the scale faithfully (19.99, 20.00), matching the interpreter.

Implementations

impl LogosDecimal

pub fn from_i64(n: i64) -> Self

A whole integer as a scale-0 decimal (5 → "5").

pub fn parse(s: &str) -> Self

Parse the exact value from its literal text ("19.99"). Panics on malformed input, which the LOGOS front-end has already rejected before codegen.

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

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

pub fn mul(&self, other: &LogosDecimal) -> LogosDecimal

pub fn to_rational(&self) -> LogosRational

The exact rational view (coeff / 10^scale) — the bridge ÷ widens through.

pub fn div_exact(&self, other: &LogosDecimal) -> LogosRational

Exact division, widening to a LogosRational (base-10 division need not terminate). Panics on a zero divisor, mirroring integer / 0.

pub fn abs(&self) -> LogosDecimal

The exact absolute value (scale preserved).

Trait Implementations

impl Clone for LogosDecimal

fn clone(&self) -> LogosDecimal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogosDecimal

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

Formats the value using the given formatter.

impl Display for LogosDecimal

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

impl From<i64> for LogosDecimal

fn from(n: i64) -> Self

Converts to this type from the input type.

Feeds a slice of this type into the given Hasher.

impl IntoRate for LogosDecimal

fn into_rate(self) -> Rational

impl Ord for LogosDecimal

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

impl PartialEq for LogosDecimal

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

fn partial_cmp(&self, other: &LogosDecimal) -> 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
