Struct Pitch 

pub struct Pitch(/* private fields */);

A MIDI note number, 0 through 127. Middle C (o4 c) is 60 and A4 (440 Hz) is 69.

Implementations

impl Pitch

pub const A4: Pitch

pub const C4: Pitch

pub fn new(midi: u8) -> Result<Self>

pub fn from_name(letter: char, accidental: i8, octave: i8) -> Result<Self>

A note letter a..g, a number of semitones to raise (1 for sharp, -1 for flat) and an octave, where octave 4 starts at middle C.

pub fn midi(self) -> u8

pub fn frequency(self) -> f64

Equal-tempered frequency with A4 at 440 Hz.

Trait Implementations

impl PartialEq for Pitch

fn eq(&self, other: &Pitch) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Pitch

fn partial_cmp(&self, other: &Pitch) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
