Struct RationalTime 

pub struct RationalTime { /* private fields */ }

Exact rational representation of time (seconds as numerator/denominator). Prevents floating-point accumulation drift over long recordings.

Implementations

impl RationalTime

pub const ZERO: Self

pub fn new(numerator: u64, denominator: u64) -> DspResult<Self>

pub fn from_seconds_f64(seconds: f64) -> DspResult<Self>

Time from a decimal number of seconds, exact for its shortest decimal form (12.5 → 25/2).

pub fn checked_add(&self, other: &Self) -> Option<Self>

self + other, or None on u64 overflow.

pub fn from_samples(sample_index: u64, rate: SampleRate) -> DspResult<Self>

Exact time of sample_index at rate (fractional rates included, no drift).

pub fn as_ratio(&self) -> Ratio<u64>

The time as an exact fraction of seconds.

pub fn as_seconds_f64(&self) -> f64

pub fn as_duration(&self) -> Duration

pub fn to_sample_index(&self, rate: SampleRate) -> u64

Index of the sample at or before this time at rate (exact).
