结构体 CaptureControl 

pub struct CaptureControl<T: GraphicsCaptureApiHandler + Send + 'static, E> { /* private fields */ }

用于控制捕获会话

实现

impl<T: GraphicsCaptureApiHandler + Send + 'static, E> CaptureControl<T, E>

pub const fn new( thread_handle: JoinHandle<Result<(), GraphicsCaptureApiError<E>>>, halt_handle: Arc<AtomicBool>, callback: Arc<Mutex<T>>, ) -> Self

构造一个新的 CaptureControl。

pub fn is_finished(&self) -> bool

检查捕获线程是否已结束。

pub fn into_thread_handle( self, ) -> JoinHandle<Result<(), GraphicsCaptureApiError<E>>>

获取捕获线程的 join 句柄。

pub fn halt_handle(&self) -> Arc<AtomicBool>

获取用于暂停捕获线程的 halt 句柄。

pub fn callback(&self) -> Arc<Mutex<T>>

获取用于直接调用结构体方法的回调结构体。

pub fn wait(self) -> Result<(), CaptureControlError<E>>

等待捕获线程停止。

Errors

• CaptureControlError::FailedToJoinThread when joining the internal thread fails
• CaptureControlError::ThreadHandleIsTaken when the thread handle was previously taken via CaptureControl::into_thread_handle

pub fn stop(self) -> Result<(), CaptureControlError<E>>

优雅地请求捕获线程停止，并等待其完成。

This posts a WM_QUIT to the capture thread and joins it.

Errors

• CaptureControlError::FailedToPostThreadMessage when posting WM_QUIT to the thread fails and the thread is still running
• CaptureControlError::FailedToJoinThread when joining the internal thread fails
• CaptureControlError::ThreadHandleIsTaken when the thread handle was previously taken via CaptureControl::into_thread_handle
