Struct audio_processor_standalone_midi::host::MidiHost

pub struct MidiHost { /* private fields */ }

Host for MIDI messages, opens all ports & forwards them onto a lock-free queue the audio-thread can pop from.

The host will close all MIDI connections on drop.

Implementations

impl MidiHost

pub fn new(handle: &Handle, capacity: usize) -> Self

Create the host, linked to GC Handle and with queue capacity of messages.

pub fn default_with_handle(handle: &Handle) -> Self

Create the host with default 100 capacity

pub fn default_with_queue(handle: &Handle, queue: MidiMessageQueue) -> Self

Build a MidiHost with a pre-built queue

pub fn messages(&self) -> &MidiMessageQueue

Get a reference to the message queue

pub fn start_midi(&mut self) -> Result<(), MidiError>

Start the MIDI connections

pub fn virtual_port_name(&self) -> String

For integration testing purposes MidiHost starts a virtual input which it’ll also connect into. This input contains the PID of the host process.

Generating this name dynamically avoids flakiness in integration tests.
