Struct NotesMap

pub struct NotesMap { /* private fields */ }

Effectively maps notes to midi and backwards.

Example

use musical_note::{NotesMap, NoteName, Accidental};
let map = NotesMap::get();
assert_eq!(map.get_by_note(NoteName::F, Accidental::DoubleFlat), 3);

Implementations

impl NotesMap

pub fn get() -> &'static NotesMap

pub fn get_by_midi(&self, midi: &u8) -> &HashMap<Accidental, NoteName>

pub fn get_by_note(&self, note: NoteName, acc: Accidental) -> u8

pub fn resolve_note_for_midi( &self, note: (NoteName, Accidental), midi: u8, ) -> Option<(NoteName, Accidental)>

Accidental of “root” is not counted.

For the given note and MIDI-byte finds only possible enharmonic variant, or returns None.

For example: with the given NoteName::C and midi 2, only possible enharmonic variant is (NoteName::C, Accidental::DoubleSharp), which will be returned.

If None is returned — something goes very wrong and it is better to panic.

pub fn resolve_enharmonic( &self, accidental: Option<Accidental>, midi: u8, ) -> (NoteName, Accidental)

Trait Implementations

impl Debug for NotesMap

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

Formats the value using the given formatter.
