::fidl::WireUnownedResult< ::fuchsia_ui_composition_internal::ScreenCapture::Configure> Configure (::fuchsia_ui_composition_internal::wire::ScreenCaptureConfig ScreenCaptureConfig)Clients should first use the ['fuchsia.ui.composition/Allocator']
protocol to register a BufferCollection.
Similarly, the clients are responsible for specifying a buffer big
enough for the image. If the buffer is too small, an
attempt will be made to render the image, however, it will not be
guaranteed to contain the complete image.
Caller provides the backing storage for FIDL message via an argument to `.buffer()`.
::fidl::WireUnownedResult< ::fuchsia_ui_composition_internal::ScreenCapture::GetNextFrame> GetNextFrame ()[`GetNextFrame`] returns the latest unseen-by-the-client frame as soon
as possible. On the first call to [`GetNextFrame`] and any subsequent
calls that have not recieved the previous expected requested frame,
[`GetNextFrame`] will return immediately with the last frame to be
rendered. If the client had requested the previous frame, the server
will wait until the next frame is produced to return.
After the client finishes processing the returned buffer, they should
drop the eventpair to signal to the server that the buffer can be
re-used.
It is invalid to call [`GetNextFrame`] while a previous call is still
pending. Doing so will return a BAD_HANGING_GET error and cause the
channel to close.
