Enum wayland_protocols::wlr::unstable::screencopy::v1::server::zwlr_screencopy_frame_v1::Request

#[non_exhaustive]pub enum Request {

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future 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 and zwlr_screencopy_frame_v1.linux_dmabuf. 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 received this object cannot be used any longer.

CopyWithDamage

copy the frame when it's damaged

Same as copy, except it waits until there is damage to copy.

Only available since version 2 of the interface

Fields of CopyWithDamage

buffer: WlBuffer
