Struct Capture 

pub struct Capture {
    stop: Arc<AtomicBool>,
    reader: Option<JoinHandle<()>>,
    device: Device,
}

A live capture: the device is open and on_block is being fed.

The stream itself lives on the reader thread, because cpal::Stream is neither Send nor Sync and dropping it is what releases the device.

Fields

stop: Arc<AtomicBool>

reader: Option<JoinHandle<()>>

device: Device

The input this capture is recording from, as open resolved it: the system default when the caller named none.

Implementations

impl Capture

pub fn device(&self) -> &Device

The input this capture opened.

The one place a host learns what the system default IS: naming no device is resolved here, and nothing upstream sees the choice.

pub fn stop(self)

Release the device and wait for the reader to finish.

fn signal(&self)

fn join(&mut self)

Trait Implementations

impl Drop for Capture

fn drop(&mut self)

A capture dropped without Capture::stop still releases the device: the handle owns no other way out.

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.
