Enum ViewExtensionError

pub enum ViewExtensionError {
    WindowNotFound(WindowNotFound),
    WindowNotHeaded(WindowId),
    NotOpenInViewProcess(WindowId),
    ViewProcessOffline(ViewProcessOffline),
    Api(ApiExtensionRecvError),
}

Error calling a view-process API extension associated with a window or renderer.

Variants

WindowNotFound(WindowNotFound)

Window is not open in the WINDOWS service.

WindowNotHeaded(WindowId)

Window must be headed to call window extensions.

Api(ApiExtensionRecvError)
