Enum CaptureControlError 

pub enum CaptureControlError<E> {
    FailedToJoinThread,
    ThreadHandleIsTaken,
    FailedToPostThreadMessage,
    StoppedHandlerError(E),
    GraphicsCaptureApiError(GraphicsCaptureApiError<E>),
}

Errors that can occur while controlling a running capture session via CaptureControl.

This error wraps lower-level errors from the Windows Graphics Capture pipeline, as well as thread-control failures when starting/stopping the background capture thread.

Variants

FailedToJoinThread

Joining the background capture thread failed (panic or OS-level join error).

Returned by CaptureControl::wait and CaptureControl::stop if the internal thread panicked or could not be joined.

ThreadHandleIsTaken

The std::thread::JoinHandle was already taken out of the struct (for example by calling CaptureControl::into_thread_handle) so the operation cannot proceed.

FailedToPostThreadMessage

Failed to post a WM_QUIT message to the capture thread to request shutdown.

This can happen if the thread is no longer alive or Windows refuses the message.

StoppedHandlerError(E)

The user-provided handler returned an error after capture stopped.

This variant carries the handler’s error type.

GraphicsCaptureApiError(GraphicsCaptureApiError<E>)

A lower-level error from the graphics capture pipeline.

Wraps GraphicsCaptureApiError.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl<E> From<GraphicsCaptureApiError<E>> for CaptureControlError<E>

fn from(source: GraphicsCaptureApiError<E>) -> Self

Converts to this type from the input type.
