The ShadowRoot trait.

Required Associated Types

type ConcreteNode: TNode<ConcreteShadowRoot = Self>

The concrete node type.

Required Methods

fn as_node(&self) -> Self::ConcreteNode

Get this ShadowRoot as a node.

fn host(&self) -> <Self::ConcreteNode as TNode>::ConcreteElement

Get the shadow host that hosts this ShadowRoot.

fn style_data<'a>(&self) -> Option<&'a CascadeData>

where Self: 'a,

Get the style data for this ShadowRoot.

Provided Methods

fn parts<'a>(&self) -> &[<Self::ConcreteNode as TNode>::ConcreteElement]

where Self: 'a,

Get the list of shadow parts for this shadow root.

fn elements_with_id<'a>( &self, _id: &AtomIdent, ) -> Result<&'a [<Self::ConcreteNode as TNode>::ConcreteElement], ()>

where Self: 'a,

Get a list of elements with a given ID in this shadow root, sorted by tree position.

Can return an error to signal that this list is not available, or also return an empty slice.

fn implicit_scope_for_sheet( &self, _sheet_index: usize, ) -> Option<ImplicitScopeRoot>

Get the implicit scope for a stylesheet in given index.
