Struct rimd::SMFBuilder [−] [src]

pub struct SMFBuilder {
    // some fields omitted
}

An SMFBuilder can be used to create an SMF file. This is done by adding tracks to the builder via add_track and then adding events to each track.

Methods

impl SMFBuilder

fn new() -> SMFBuilder

Create a new SMFBuilder. Initially the builder will have no tracks

fn num_tracks(&self) -> usize

Get the number of tracks currenly in the builder

fn add_track(&mut self)

Add new a track to this builder

fn add_static_track<'a, I>(&mut self, track: I) where I: Iterator<Item=&'a AbsoluteEvent>

Add a static track to the builder (note this will clone all events in the passed iterator)

Set the copyright for the track at index track. This will also cause a copyright meta event to be inserted.

Panics

Panics if track is >= to the number of tracks in this builder, or if the track already has a copyright set.

fn set_name(&mut self, track: usize, name: String)

Set the name for the track at index track. This will also cause a name meta event to be inserted.

Panics

Panics if track is >= to the number of tracks in this builder, or if the track already has a name set.

fn add_midi_abs(&mut self, track: usize, time: u64, msg: MidiMessage)

Add a midi message to track at index track at absolute time time.

Panics

Panics if track is >= to the number of tracks in this builder

fn add_midi_rel(&mut self, track: usize, delta: u64, msg: MidiMessage)

Add a midi message to track at index track at delta ticks after the last message (or at delta if no current messages exist)

Panics

Panics if track is >= to the number of tracks in this builder

fn add_meta_abs(&mut self, track: usize, time: u64, event: MetaEvent)

Add a meta event to track at index track at absolute time time.

Panics

Panics if track is >= to the number of tracks in this builder

fn add_meta_rel(&mut self, track: usize, delta: u64, event: MetaEvent)

Add a meta event to track at index track at delta ticks after the last message (or at delta if no current messages exist)

Panics

Panics if track is >= to the number of tracks in this builder

fn add_event(&mut self, track: usize, event: TrackEvent)

Add a TrackEvent to the track at index track. The event will be added at event.vtime after the last event currently in the builder for the track.

Panics

Panics if track is >= to the number of tracks in this builder

fn result(self) -> SMF

Generate an SMF file with the events that have been added to the builder
