Struct OutputMidiConsumer 

pub struct OutputMidiConsumer { /* private fields */ }

A Send + Sync handle for draining the MIDI a plugin emits (arpeggiators, MPE, MIDI thru, …) without locking the audio thread.

Obtain one from Plugin::output_midi_handle. The plugin’s audio thread pushes emitted events into a lock-free bounded queue; this handle pops them from any other thread (e.g. a UI poll loop) with no lock on either side — the lock-free counterpart to the audio-thread drain in Plugin::take_output_midi. When the queue is full the oldest event is dropped, so a host that stops polling can’t grow it without bound.

Available for in-process plugins; the process-isolation path returns None (output MIDI crosses the boundary in the IPC responses instead).

Implementations

impl OutputMidiConsumer

pub fn pop(&self) -> Option<MidiEvent>

Pop the oldest emitted event, or None if none are queued. Lock-free.

pub fn drain(&self) -> Vec<MidiEvent>

Drain all currently queued events in emission order into a Vec. Lock-free pops; the returned Vec allocates on the calling thread (intended for a UI/control thread, not the audio thread — use pop in a loop to stay allocation-free).

Trait Implementations

impl Clone for OutputMidiConsumer

fn clone(&self) -> OutputMidiConsumer

Returns a duplicate of the value.

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

Performs copy-assignment from source.
