Required Methods§

Source

fn as_image(self) -> Option<(Option<Arc<Image>>, PhysicalSize<f64>)>

Returns the image if it’s loaded, and its size in image pixels adjusted for image_density.

Source

fn as_canvas(self) -> Option<(CanvasInfo, PhysicalSize<f64>)>

Source

fn as_iframe(self) -> Option<(PipelineId, BrowsingContextId)>

Source

fn as_video(self) -> Option<(Option<ImageKey>, Option<PhysicalSize<f64>>)>

Source

fn as_typeless_object_with_data_attribute(self) -> Option<String>

Source

fn style(self, context: &LayoutContext<'_>) -> ServoArc<ComputedValues>

Source

fn layout_data_mut(self) -> AtomicRefMut<'dom, InnerDOMLayoutData>

Source

fn layout_data(self) -> Option<AtomicRef<'dom, InnerDOMLayoutData>>

Source

fn element_box_slot(&self) -> BoxSlot<'dom>

Source

fn pseudo_element_box_slot(&self, which: PseudoElement) -> BoxSlot<'dom>

Source

fn unset_pseudo_element_box(self, which: PseudoElement)

Source

fn unset_all_boxes(self)

Remove boxes for the element itself, and its :before and :after if any.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
