What a reduction is asked for: music21’s arguments to ChordReducer.run.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

maximum_number_of_chords: usize

How many chords a measure may keep: music21’s maximumNumberOfChords, three by default.

closed_position: bool

Whether every chord is written in closed position afterwards: music21’s closedPosition.

force_octave: Option<IntegerType>

The octave a chord in closed position has its lowest note in, or its own octave with None: music21’s forceOctave, 4 by default.

allowable_chords: Vec<Chord>

Chords whose interval classes count as consonant however they sound: music21’s allowableChords.

forbidden_chords: Vec<Chord>

Chords whose interval classes count as dissonant however they sound: music21’s forbiddenChords.

remove_dissonances: bool

Whether the notes above the bass of a dissonant moment go before the measures are weighed: music21’s removeDissonances, off by default.

weight_algorithm: SliceWeigher

What each slice of a measure weighs: music21’s weightAlgorithm, slice_weight by default.

Trait Implementations

impl Clone for ReductionOptions

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReductionOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ReductionOptions

fn default() -> Self

Returns the “default value” for a type.
