Enum Key 

pub enum Key {
    Wildcard,
    Number(u8),
}

The key number of the note. This is also sometimes referred to as the “pitch”.

Same as MIDI1 Key Number (60 == Middle C)

Variants

Wildcard

The note can belong to any key.

Number(u8)

The note’s key number, in 0..127. Same as MIDI1 Key Number (60 == Middle C)

Implementations

impl Key

pub const MIDDLE_C: Self

The key number equal to Middle C (60)

pub const fn number(&self) -> Option<u8>

Return the key number if it exists, or return None if it is a wildcard (the note can belong to any key).

pub const fn number_or_middle_c(&self) -> u8

Return the key number if it exists, or return Middle C (60) if it is a wildcard.

pub const fn is_wildcard(&self) -> bool

Returns true if this is a wildcard (the note can belong to any channel).

Trait Implementations

impl Clone for Key

fn clone(&self) -> Key

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Key

impl Debug for Key

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

Formats the value using the given formatter.

impl Eq for Key

impl Hash for Key

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl Ord for Key

fn cmp(&self, other: &Key) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Key

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Key

fn partial_cmp(&self, other: &Key) -> 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.
