A meta event in a Standard Midi File

Variants

SequenceNumber(u16)

Must occur at the start of a track, and specifies the sequence number of the track. In a MultiSong file, this is the “pattern” number that identifies the song for cueing purposes.

Text(String)

Any text, describing anything

Copyright(String)

A copyright notice

TrackName(String)

The name of the track

InstrumentName(String)

The name of the instrument used in the track

Lyric(String)

A lyric. See RP-017 for guidance on the use of this meta event.

Marker(String)

Normally only used in a SingleTrack file, or the first track of a MultiTrack file. Used to mark significant points in the music.

CuePoint(String)

A description of something happening at a point in time

ChannelPrefix(Channel)

The MIDI channel that the following track events are intended for. Effective until the next event that specifies a channel.

EndOfTrack

Marks the end of a track. This event is not optional. It must be the last event in every track.

SetTempo(u32)

The tempo in microseconds per quarter note.

SmpteOffset(HighResTimeCode)

If present, the time at which the track is supposed to start. Should be present at the start of the track.

TimeSignature(FileTimeSignature)

A time signature.

KeySignature(KeySignature)

A key signature.

SequencerSpecific(Vec<u8>)

A chunk of data that is specific to the sequencer that created the file.

Unknown

Any other meta event that is not recognized

Fields

meta_type: u8

data: Vec<u8>

Trait Implementations

impl Clone for Meta

fn clone(&self) -> Meta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Meta

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

Formats the value using the given formatter.

impl PartialEq for Meta

fn eq(&self, other: &Meta) -> 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.

impl StructuralPartialEq for Meta
