Struct wayland_protocols::wp::presentation_time::client::wp_presentation_feedback::WpPresentationFeedback

pub struct WpPresentationFeedback { /* private fields */ }

presentation time feedback event

A presentation_feedback object returns an indication that a wl_surface content update has become visible to the user. One object corresponds to one content update submission (wl_surface.commit). There are two possible outcomes: the content update is presented to the user, and a presentation timestamp delivered; or, the user did not see the content update because it was superseded or its surface destroyed, and the content update is discarded.

Once a presentation_feedback object has delivered a ‘presented’ or ‘discarded’ event it is automatically destroyed.

See also the Event enum for this interface.

impl Borrow<ObjectId> for WpPresentationFeedback

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for WpPresentationFeedback

fn clone(&self) -> WpPresentationFeedback

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WpPresentationFeedback

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for WpPresentationFeedback

fn hash<H: Hasher>(&self, state: &mut H)

impl PartialEq<Weak<WpPresentationFeedback>> for WpPresentationFeedback

fn eq(&self, other: &Weak<WpPresentationFeedback>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
