Struct ServoThreadSafeLayoutNode 

pub struct ServoThreadSafeLayoutNode<'dom> { /* private fields */ }

A wrapper around a ServoLayoutNode that can be used safely on different threads. It’s very important that this never mutate anything except this wrapped node and never access any other node apart from its parent.

Implementations

impl<'dom> ServoThreadSafeLayoutNode<'dom>

pub fn new(node: ServoLayoutNode<'dom>) -> Self

Creates a new ServoThreadSafeLayoutNode from the given ServoLayoutNode.

pub fn is_single_line_text_input(&self) -> bool

Whether this is a container for the text within a single-line text input. This is used to solve the special case of line height for a text entry widget. https://html.spec.whatwg.org/multipage/#the-input-element-as-a-text-entry-widget

pub fn selected_style( &self, context: &SharedStyleContext<'_>, ) -> Arc<ComputedValues>

Trait Implementations

impl<'dom> Clone for ServoThreadSafeLayoutNode<'dom>

fn clone(&self) -> ServoThreadSafeLayoutNode<'dom>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'dom> Debug for ServoThreadSafeLayoutNode<'dom>

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

Formats the value using the given formatter.

impl NodeInfo for ServoThreadSafeLayoutNode<'_>

fn is_element(&self) -> bool

Whether this node is an element.

fn is_text_node(&self) -> bool

Whether this node is a text node.

impl<'dom> PartialEq for ServoThreadSafeLayoutNode<'dom>

fn eq(&self, other: &ServoThreadSafeLayoutNode<'dom>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'dom> ThreadSafeLayoutNode<'dom> for ServoThreadSafeLayoutNode<'dom>

fn set_uses_content_attribute_with_attr( &self, uses_content_attribute_with_attr: bool, )

Safety

This function accesses and modifies the underlying DOM object and should not be used by more than a single thread at once.

type ConcreteNode = ServoLayoutNode<'dom>

type ConcreteThreadSafeLayoutElement = ServoThreadSafeLayoutElement<'dom>

type ConcreteElement = ServoLayoutElement<'dom>

type ChildrenIterator = ServoThreadSafeLayoutNodeChildrenIterator<'dom>

fn opaque(&self) -> OpaqueNode

Converts self into an OpaqueNode.

fn pseudo_element_chain(&self) -> PseudoElementChain

fn type_id(&self) -> Option<LayoutNodeType>

Returns the type ID of this node. Returns None if this is a pseudo-element; otherwise, returns Some.

fn parent_style(&self, context: &SharedStyleContext<'_>) -> Arc<ComputedValues>

Returns the style for a text node. This is computed on the fly from the parent style to avoid traversing text nodes in the style system.

fn initialize_layout_data<RequestedLayoutDataType: LayoutDataTrait>(&self)

Initialize this node with empty opaque layout data.

fn debug_id(self) -> usize

fn children(&self) -> LayoutIterator<Self::ChildrenIterator>

Returns an iterator over this node’s children.

fn as_element(&self) -> Option<ServoThreadSafeLayoutElement<'dom>>

Returns a ThreadSafeLayoutElement if this is an element, None otherwise.

fn as_html_element(&self) -> Option<ServoThreadSafeLayoutElement<'dom>>

Returns a ThreadSafeLayoutElement if this is an element in an HTML namespace, None otherwise.

fn style_data(&self) -> Option<&'dom StyleData>

Get the StyleData for this node. Returns None if the node is unstyled.

fn layout_data(&self) -> Option<&'dom GenericLayoutData>

Get the layout data of this node, attempting to downcast it to the desired type. Returns None if there is no layout data or it isn’t of the desired type.

fn unsafe_get(self) -> Self::ConcreteNode

Returns access to the underlying LayoutNode. This is breaks the abstraction barrier of ThreadSafeLayout wrapper layer, and can lead to races if not used carefully.

fn text_content(self) -> Cow<'dom, str>

Get the text content of this node, if it is a text node.

fn selection(&self) -> Option<SharedSelection>

If this node manages a selection, this returns the shared selection for the node.

fn image_url(&self) -> Option<ServoUrl>

If this is an image element, returns its URL. If this is not an image element, fails.

fn image_density(&self) -> Option<f64>

If this is an image element, returns its current-pixel-density. If this is not an image element, fails.

fn showing_broken_image_icon(&self) -> bool

Whether or not this is an image element that is showing a broken image icon.

fn image_data(&self) -> Option<(Option<Image>, Option<ImageMetadata>)>

If this is an image element, returns its image data. Otherwise, returns None.

fn canvas_data(&self) -> Option<HTMLCanvasData>

fn media_data(&self) -> Option<HTMLMediaData>

fn svg_data(&self) -> Option<SVGElementData<'dom>>

fn iframe_browsing_context_id(&self) -> Option<BrowsingContextId>

If this node is an iframe element, returns its browsing context ID. If this node is not an iframe element, fails. Returns None if there is no nested browsing context.

fn iframe_pipeline_id(&self) -> Option<PipelineId>

If this node is an iframe element, returns its pipeline ID. If this node is not an iframe element, fails. Returns None if there is no nested browsing context.

fn get_span(&self) -> Option<u32>

fn get_colspan(&self) -> Option<u32>

fn get_rowspan(&self) -> Option<u32>

fn with_pseudo_element_chain( &self, pseudo_element_chain: PseudoElementChain, ) -> Self

fn style(&self, context: &SharedStyleContext<'_>) -> Arc<ComputedValues>

fn is_content(&self) -> bool

Returns true if this node contributes content. This is used in the implementation of empty_cells per CSS 2.1 § 17.6.1.1.

fn with_pseudo(&self, pseudo_element_type: PseudoElement) -> Option<Self>
