Trait to wrap system specific helpers for writing to endpoint playback buffers.

Required Methods

fn new(guest_period_bytes: usize) -> Self

where Self: Sized,

fn endpoint_period_bytes(&self) -> usize

Returns the period of the endpoint device.

Provided Methods

fn copy_to_buffer( &mut self, dst_buf: &mut AsyncPlaybackBuffer<'_>, reader: &mut Reader ) -> Result<usize, Error>

Read audio samples from the tx virtqueue.
