[−][src]Function atm::utils::gen_sequences

pub fn gen_sequences(
    notes: &MIDINoteVec, 
    length: u32
) -> MultiProduct<Iter<MIDINote>>

Generate melodies of length length containing the notes in provided note set notes. In other words, generate the cartesion product of notes with itself length times.

Arguments:

notes: set of MIDI notes (see: libatm::MIDINote)
length: length of sequences to generate

Examples

// Create MIDI note set
let note_set = "C:4,C:4,D:4,E:4,F:4,G:5".parse::<libatm::MIDINoteVec>().unwrap();
// Create iterable over all possible melodies, which in this example would be
// 6 ^ 8 = 1,679,616 instances of `Vec<&libatm::MIDINote>`.
let melodies = atm::utils::gen_sequences(&note_set, 8);
assert_eq!(1679616usize, melodies.count())
