RationalTime

eqiora::kernel

Struct RationalTime 

pub struct RationalTime { /* private fields */ }
Description

A non-negative rational number of seconds in reduced form.

Model clocks use exact rational time so multi-rate coincidences never depend on floating-point equality. Physical integration time may still use floating-point values after realization.

Implementations§

§

impl RationalTime

Signature links:§RationalTime

pub const ZERO: RationalTime

Signature links:ZERORationalTime

Zero seconds.

pub fn new(numerator: u64, denominator: u64) -> Result<RationalTime, Diagnostic>

Signature links:newu64u64ResultRationalTimeDiagnostic

Construct a canonical non-negative rational number of seconds.

§Errors

Returns EQ0305 when denominator is zero.

pub const fn numerator(self) -> u64

Signature links:numeratoru64

Numerator of the reduced seconds fraction.

pub const fn denominator(self) -> u64

Signature links:denominatoru64

Denominator of the reduced seconds fraction.

pub fn as_seconds_f64(self) -> f64

Signature links:as_seconds_f64f64

Convert to seconds for numerical realization.

pub const fn is_zero(self) -> bool

Signature links:is_zerobool

Whether the exact time is zero.

pub fn checked_add( self, other: RationalTime, ) -> Result<RationalTime, Diagnostic>

Signature links:checked_addRationalTimeResultRationalTimeDiagnostic

Add two exact model-time values without silently overflowing.

§Errors

Returns EQ0305 when the reduced result cannot be represented by the u64 numerator/denominator wire contract.
