Variants

Copy

copy the frame

Copy the frame to the supplied buffer. The buffer must have a the correct size, see zwlr_screencopy_frame_v1.buffer. The buffer needs to have a supported format.

If the frame is successfully copied, a "flags" and a "ready" events are sent. Otherwise, a "failed" event is sent.

Fields of Copy

buffer: WlBuffer

Destroy

delete this object, used or not

Destroys the frame. This request can be sent at any time by the client.

This is a destructor, once sent this object cannot be used any longer.

Trait Implementations

impl MessageGroup for Request
