Required Methods§

Source

fn as_image(&self) -> Option<(ImageInfo, PhysicalSize<f64>)>

Returns the relevant data wrapping into respective struct and its size in pixels.

Source

fn inner_layout_data_mut( &self, ) -> Option<AtomicRefMut<'dom, InnerDOMLayoutData>>

Source

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

Source

fn unset_all_boxes(&self)

Remove boxes for the element itself, and all of its pseudo-element boxes.

Source

fn fragments_for_pseudo( &self, pseudo_element: Option<PseudoElement>, ) -> Vec<Fragment>

Source

fn with_layout_box_base_including_pseudos( &self, callback: impl Fn(&LayoutBoxBase), )

Source

fn repair_style(&self, context: &SharedStyleContext<'_>)

Source

fn isolates_damage_for_damage_propagation(&self) -> bool

Whether or not this node isolates downward flowing box tree rebuild damage and fragment tree layout cache damage. Roughly, this corresponds to independent formatting context boundaries.

The node’s boxes themselves will be rebuilt, but not the descendant node’s boxes.
The node’s fragment tree layout will be rebuilt, not the descendent node’s fragment tree layout cache.

When this node has no box yet, false is returned.

Source

fn rebuild_box_tree_from_independent_formatting_context( &self, layout_context: &LayoutContext<'_>, ) -> bool

Try to re-run box tree reconstruction from this point. This can succeed if the node itself is still valid and isolates box tree damage from ancestors (for instance, if it starts an independent formatting context). Note: This assumes that no ancestors have box damage.

Returns true if box tree reconstruction was sucessful and false otherwise.
