Enum wayland_protocols::presentation_time::server::wp_presentation::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.

Destroy

unbind from the presentation interface

Informs the server that the client will no longer be using this protocol object. Existing objects created by this object are not affected.

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

Feedback

request presentation feedback information

Request presentation feedback for the current content submission on the given surface. This creates a new presentation_feedback object, which will deliver the feedback information once. If multiple presentation_feedback objects are created for the same submission, they will all deliver the same information.

For details on what information is returned, see the presentation_feedback interface.

Fields of Feedback

surface: WlSurfacecallback: Main<WpPresentationFeedback>
