commit timing

When a compositor latches on to new content updates it will check for any number of requirements of the available content updates (such as fences of all buffers being signalled) to consider the update ready.

This protocol provides a method for adding a time constraint to surface content. This constraint indicates to the compositor that a content update should be presented as closely as possible to, but not before, a specified time.

This protocol does not change the Wayland property that content updates are applied in the order they are received, even when some content updates contain timestamps and others do not.

To provide timestamps, this global factory interface must be used to acquire a wp_commit_timing_v1 object for a surface, which may then be used to provide timestamp information for commits.

Warning! The protocol described in this file is currently in the testing phase. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes can only be done by creating a new major version of the extension.

This interface has no events.

Implementations

impl WpCommitTimingManagerV1

pub fn destroy(&self)

unbind from the commit timing interface

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

pub fn get_timer<U: Send + Sync + 'static, D: Dispatch<WpCommitTimerV1, U> + 'static>( &self, surface: &WlSurface, qh: &QueueHandle<D>, udata: U, ) -> WpCommitTimerV1

request commit timer interface for surface

Establish a timing controller for a surface.

Only one commit timer can be created for a surface, or a commit_timer_exists protocol error will be generated.

Trait Implementations

impl Borrow<ObjectId> for WpCommitTimingManagerV1

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for WpCommitTimingManagerV1

fn clone(&self) -> WpCommitTimingManagerV1

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WpCommitTimingManagerV1

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

Formats the value using the given formatter.

impl Hash for WpCommitTimingManagerV1

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Weak<WpCommitTimingManagerV1>> for WpCommitTimingManagerV1

fn eq(&self, other: &Weak<WpCommitTimingManagerV1>) -> 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.
