Struct CpalBackend 

pub struct CpalBackend { /* private fields */ }

Real audio backend using cpal.

Implementations

impl CpalBackend

pub fn new(_desired_sample_rate: u32, _desired_buffer_size: u32) -> Result<Self>

Create a new cpal backend. Does NOT start the stream yet.

pub fn start<F>(&mut self, callback: F) -> Result<()>

where F: FnMut(&mut [f32]) + Send + 'static,

Start the audio stream, calling callback for each buffer. The callback receives an interleaved f32 buffer: [L, R, L, R, …]

pub fn stop(&mut self)

pub fn sample_rate(&self) -> u32

pub fn channels(&self) -> u16

Trait Implementations

impl Drop for CpalBackend

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
