Struct NullBackend 

pub struct NullBackend { /* private fields */ }

A passive I/O backend that writes to nowhere and reads zeros.

Implements both IoCapture and IoPlayback as no-ops. Useful as a placeholder for the unused direction in input-only or output-only scenarios.

Implementations

impl NullBackend

pub fn new(channels: usize) -> Self

Create a null backend with the given number of channels.

Trait Implementations

impl IoCapture for NullBackend

fn read_input(&self, _channel: usize, dst: &mut [f32]) -> usize

Read captured samples for one channel into dst.

fn num_input_channels(&self) -> usize

Number of capture channels.

impl IoPlayback for NullBackend

fn write_output(&self, _channel: usize, _src: &[f32]) -> usize

Write output samples for one channel from src.

fn num_output_channels(&self) -> usize

Number of playback channels.
