Struct MicCapturePipeline 

pub struct MicCapturePipeline {
    cancel: Arc<AtomicBool>,
    handle: Option<JoinHandle<()>>,
}

Mic-pipeline worker handle. Owns the spawned thread and a cooperative cancel flag; Drop cancels + joins so a panicking caller can never leave a zombie gst child behind.

Fields

cancel: Arc<AtomicBool>

handle: Option<JoinHandle<()>>

Implementations

impl MicCapturePipeline

pub fn spawn( app: AppHandle, mic_id: String, native_id: String, mixer: Option<SharedAudioMixer>, ) -> Result<Self, MicError>

Spawn the worker thread. Returns immediately; the worker transitions [MicLifecycle] to Running once next_chunk() first succeeds (after any macOS permission prompt resolves).

mixer controls whether the worker forwards samples into the recorder’s shared [AudioMixer]. Pass None for preview (meter only — what the picker uses); pass Some(mixer) for recording. Mirror of the SCK system-audio start vs. start_with_mixer split. Without this distinction, preview samples accumulate in the mixer and contaminate the next recording.

Errors

Returns Err only if the OS refuses to spawn a thread (effectively never happens). gst-side errors are handled inside the worker — the worker logs via tracing::error! and resets the lifecycle to Idle so the UI shows a recovery state.

Trait Implementations

impl Drop for MicCapturePipeline

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.
