}

A part cut into segments of groupings, ready to transcribe: music21’s BrailleSegment.

Fields

groupings: BTreeMap<SegmentKey, BrailleElementGrouping>

The groupings, by key.

options: SegmentOptions

The options it is written with.

descending_chords: Option<bool>

Whether chords are written from the top down, as the clefs met so far say.

end_hyphen: bool

Whether the segment ends in the middle of a measure.

begins_mid_measure: bool

Whether it begins in the middle of a measure.

contexts: Vec<NoteContext>

What music21 marked on each of the part’s leaves.

Implementations

impl BrailleSegment

pub fn add_grouping_attributes(&mut self)

Repeated measures counted, key signatures given their predecessors, full measures’ rests marked and each grouping told the signatures and options in force: music21’s addGroupingAttributes.

pub fn fix_articulations(&mut self)

Runs of three or more notes with one articulation written with it doubled on the first and once on the last, and a staccato or tenuto over a tie written as a short slur: music21’s fixArticulations.

impl BrailleSegment

pub fn transcribe(&mut self) -> Result<String>

The segment in braille: its heading and first measure number, then each grouping in turn: music21’s transcribe.

Errors

Something too wide for a line, or that music21 cannot write.

pub fn english(&self) -> String

The segment’s groupings in English, as music21’s __str__ lists them.
