Trait AudioBackend 

pub trait AudioBackend {
    // Required methods
    fn queue_samples(&mut self, samples: &[u8]);
    fn stop(&mut self);

    // Provided method
    fn queue_stereo_samples(&mut self, samples: &[u8]) { ... }
}

Trait for pushing mixed PCM samples to the host audio device.

Required Methods

fn queue_samples(&mut self, samples: &[u8])

Queue unsigned 8-bit mono PCM samples (silence = 0x80) at 22050 Hz. An empty slice signals no audio this frame.

fn stop(&mut self)

Stop audio output and release resources.

Provided Methods

fn queue_stereo_samples(&mut self, samples: &[u8])

Queue interleaved unsigned 8-bit stereo PCM samples (left, right, left, right; silence = 0x80) at 22050 Hz.

Backends that only support the historical mono path can rely on this default downmix.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
