A meta event: track-scoped information that is not transmitted over the wire, recognised types plus an Other escape hatch.

Variants

EndOfTrack

End-of-track marker.

Tempo

Tempo change expressed in microseconds per quarter note.

Fields

us_per_quarter: u32

Microseconds per quarter note.

TimeSig

Time signature.

Fields

num: u8

Numerator (beats per bar).

den_pow2: u8

Denominator as a power of two (e.g. 2 for a quarter-note beat).

clocks_per_click: u8

MIDI clocks per metronome click.

thirty_seconds_per_quarter: u8

Notated 32nd notes per quarter note.

KeySig

Key signature.

Fields

sharps_flats: i8

Number of sharps (positive) or flats (negative).

minor: bool

Whether the key is minor.

Other(MetaBucket)

Any other meta type, carried as a raw MetaBucket.

Trait Implementations

impl Clone for MetaEvent

fn clone(&self) -> MetaEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetaEvent

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

Formats the value using the given formatter.

impl Eq for MetaEvent

impl Hash for MetaEvent

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MetaEvent

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
