Returns the interval between this note and another.

use redact_composer_musical::{Interval, Note, NoteName::C};

impl Note

pub fn play(&self, velocity: u8) -> PlayNote

Creates a PlayNote element from this note, which can then be used as a Segment.

use redact_composer_core::{elements::PlayNote, timing::Timing, IntoSegment};
use redact_composer_musical::{Note, NoteName::C};

let expected_play_note = PlayNote { note: 60, velocity: 100};
let play_note = Note::from((C, 4)).play(100);
assert_eq!(play_note, expected_play_note);

let segment = play_note.into_segment(0..480);
assert_eq!(segment.element_as::<PlayNote>(), Some(&expected_play_note));
assert_eq!(segment.timing, Timing::from(0..480));
