Struct MeasureLength 

pub struct MeasureLength {
    pub numerator: u32,
    pub denominator: u32,
}

Authored length of a measure that differs from its time signature: a pickup (anacrusis), an incomplete final bar, or any irregular bar, as MuseScore’s measure len="1/4". The value is a fraction of a whole note, so 1/4 lasts one quarter-note beat.

Fields

numerator: u32

denominator: u32

Implementations

impl MeasureLength

pub const MAX_BEATS: f64 = 256.0

Largest supported measure length, in quarter-note beats.

pub fn beats(&self) -> Option<f64>

Length in quarter-note beats, or None for a zero, non-finite, or oversized fraction.

pub fn from_beats(beats: f64) -> Option<Self>

Fraction for a length in quarter-note beats, exact for binary, triplet, quintuplet and septuplet subdivisions; None for a zero, negative, or oversized length.

pub fn from_ticks(ticks: u32, divisions: u32) -> Option<Self>

Exact fraction for ticks at divisions ticks per quarter note, in lowest terms.
