Trait ScreenCaptureSource 

pub trait ScreenCaptureSource {
    // Required methods
    fn metadata(&self) -> Result<SourceMetadata>;
    fn stream(
        &self,
        foreground_executor: &ForegroundExecutor,
        frame_callback: Box<dyn Fn(ScreenCaptureFrame) + Send>,
    ) -> Receiver<Result<Box<dyn ScreenCaptureStream>>> ;

    // Provided method
    fn stream_with_termination(
        &self,
        _foreground_executor: &ForegroundExecutor,
        _frame_callback: Box<dyn Fn(ScreenCaptureFrame) + Send>,
        _termination_callback: ScreenCaptureTerminationCallback,
    ) -> Receiver<Result<Box<dyn ScreenCaptureStream>>>  { ... }
}

A source of on-screen video content that can be captured.

Required Methods

fn metadata(&self) -> Result<SourceMetadata>

Returns metadata for this source.

fn stream( &self, foreground_executor: &ForegroundExecutor, frame_callback: Box<dyn Fn(ScreenCaptureFrame) + Send>, ) -> Receiver<Result<Box<dyn ScreenCaptureStream>>>

Start capture video from this source, invoking the given callback with each frame.

Provided Methods

fn stream_with_termination( &self, _foreground_executor: &ForegroundExecutor, _frame_callback: Box<dyn Fn(ScreenCaptureFrame) + Send>, _termination_callback: ScreenCaptureTerminationCallback, ) -> Receiver<Result<Box<dyn ScreenCaptureStream>>>

Starts capture and reports its terminal state.

Startup failures are returned through the receiver. Implementations invoke termination_callback exactly once after a started stream ends, is cancelled, or fails.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
