protocol for fifo constraints

When a Wayland compositor considers applying a content update, it must ensure all the update’s readiness constraints (fences, etc) are met.

This protocol provides a way to use the completion of a display refresh cycle as an additional readiness constraint.

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.

Fields

id: ObjectId

version: u32

data: Option<Arc<dyn ObjectData>>

backend: WeakBackend

Implementations

impl WpFifoManagerV1

pub fn destroy(&self)

unbind from the manager 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_fifo<U: Send + Sync + 'static, D: Dispatch<WpFifoV1, U> + 'static>( &self, surface: &WlSurface, qh: &QueueHandle<D>, udata: U, ) -> WpFifoV1

request fifo interface for surface

Establish a fifo object for a surface that may be used to add display refresh constraints to content updates.

Only one such object may exist for a surface and attempting to create more than one will result in an already_exists protocol error. If a surface is acted on by multiple software components, general best practice is that only the component performing wl_surface.attach operations should use this protocol.

Trait Implementations

impl Borrow<ObjectId> for WpFifoManagerV1

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for WpFifoManagerV1

fn clone(&self) -> WpFifoManagerV1

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WpFifoManagerV1

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

Formats the value using the given formatter.

impl Hash for WpFifoManagerV1

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

Feeds this value into the given Hasher.

impl PartialEq<Weak<WpFifoManagerV1>> for WpFifoManagerV1

fn eq(&self, other: &Weak<WpFifoManagerV1>) -> 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.
