Struct AlsaPlaybackBridge 

pub struct AlsaPlaybackBridge<P> { /* private fields */ }

Drives an audio graph processor from an ALSA playback callback.

Implementations

impl<P: Processor> AlsaPlaybackBridge<P>

pub fn new(processor: P, spec: PcmSpec, max_block_frames: u32) -> Result<Self>

Builds a playback bridge, preparing processor for the given spec.

max_block_frames is the largest callback block the bridge will accept and must be greater than zero. The processor is prepared with the spec’s sample rate, channel count, and this block bound.

pub fn render_buffer(&mut self, frames: usize) -> Result<PcmBuffer>

Renders frames of audio into a PcmBuffer in the spec’s format.

F32 output is returned directly; I16 output is converted from the rendered F32 samples.

pub fn render_interleaved_f32(&mut self, frames: usize) -> Result<Vec<f32>>

Renders frames of audio and returns interleaved F32 samples.

Errors when frames exceeds the configured max_block_frames. The processor runs over a single ProcessBlock with a playing transport; the bridge’s sample position advances by frames.

pub fn sample_pos(&self) -> u64

Returns the running sample position across rendered blocks.

pub fn reset(&mut self)

Resets the processor, sample position, and scratch arena.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
