Struct MidiBeat 

pub struct MidiBeat { /* private fields */ }

An exact, non-negative position measured in MIDI quarter-note beats.

The reduced rational representation avoids rounding tuplets or rebased ticks. MIDI tempo always uses a quarter note as its beat unit, independent of the notated time signature.

Implementations

impl MidiBeat

pub fn new(numerator: i128, denominator: i128) -> Result<Self, MidiError>

Builds numerator / denominator quarter-note beats and reduces it.

Negative values and a zero denominator are rejected because SMF tempo timelines begin at tick zero.

pub const fn numerator(self) -> i128

Returns the reduced numerator in quarter-note beats.

pub const fn denominator(self) -> i128

Returns the reduced, positive denominator in quarter-note beats.
