Struct vst::buffer::SendEventBuffer

pub struct SendEventBuffer { /* private fields */ }

This buffer is used for sending midi events through the VST interface. The purpose of this is to convert outgoing midi events from event::Event to api::Events. It only allocates memory in new() and reuses the memory between calls.

Implementations

impl SendEventBuffer

pub fn new(capacity: usize) -> Self

Creates a buffer for sending up to the given number of midi events per frame

pub fn send_events<T: IntoIterator<Item = U>, U: WriteIntoPlaceholder>(
    &mut self,
    events: T,
    host: &mut dyn Host
)

Sends events to the host. See the fwd_midi example.

Example

fn process(&mut self, buffer: &mut AudioBuffer<f32>){
    let events: Vec<MidiEvent> = vec![
        // ...
    ];
    self.send_buffer.send_events(&events, &mut self.host);
}

pub fn store_events<T: IntoIterator<Item = U>, U: WriteIntoPlaceholder>(
    &mut self,
    events: T
)

Stores events in the buffer, replacing the buffer’s current content. Use this in process_events to store received input events, then read them in process using events.

pub fn events(&self) -> &Events

Returns a reference to the stored events

pub fn clear(&mut self)

Clears the buffer

Trait Implementations

impl Default for SendEventBuffer

fn default() -> Self

Returns the “default value” for a type.
