Struct Staff 

pub struct Staff {
    pub clef: Clef,
    pub measures: Vec<Measure>,
    pub transpose_semitones: i8,
    pub tablature: Option<TablatureConfig>,
    pub presentation: StaffPresentation,
}

Fields

clef: Clef

measures: Vec<Measure>

transpose_semitones: i8

Semitones to add to written pitch for concert pitch / MIDI output. -2 = Bb instrument (clarinet, trumpet), -9 = Eb instrument (alto sax), etc.

tablature: Option<TablatureConfig>

presentation: StaffPresentation

Implementations

impl Staff

pub fn meter_at<'a>( &'a self, measure_index: usize, default: &'a TimeSignature, ) -> &'a TimeSignature

The meter in force at measure_index: that bar’s time signature or the last one before it, else default (the score’s). A bar without its own signature continues the meter of the change before it, not the score’s opening one.

pub fn measure_beats( &self, measure_index: usize, default: &TimeSignature, ) -> f64

A bar’s length in beats: its actual_length, else the meter in force there.

pub fn new(clef: Clef) -> Self

pub fn tablature_at(&self, measure_index: usize) -> Option<TablatureConfig>

Resolve the tablature tuning and capo active at a physical measure.

A measure-local change starts at its own boundary and continues until replaced or cleared. Line-count changes are rejected by validation so the staff geometry remains stable within a system.
