Struct Background Effect State &nbsp; Copy item path

impl BackgroundEffectState

pub fn new<D>(globals: &GlobalList, qh: &QueueHandle<D>) -> Self
where D: Dispatch<ExtBackgroundEffectManagerV1, GlobalData> + 'static,

pub fn capabilities(&self) -> Option<Capability>

Capabilities advertised by the compositor.

Returns None if the compositor has not yet advertised capabilities.

pub fn get_background_effect<D>( &self, surface: &WlSurface, qh: &QueueHandle<D>, ) -> Result<ExtBackgroundEffectSurfaceV1, GlobalError>
where D: Dispatch<ExtBackgroundEffectSurfaceV1, GlobalData> + 'static,

Get ext_background_effect_surface_v1 for a given wl_surface.

Returns error if ext_background_effect_manager_v1 global is not present.

pub fn ext_background_effect_manager_v1( &self, ) -> Result<&ExtBackgroundEffectManagerV1, GlobalError>

The ext_background_effect_manager_v1 global, if any.

impl !UnwindSafe for BackgroundEffectState

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
