Fields

htmlelement: HTMLElement

assigned_nodes: RefCell<Vec<Slottable>>

https://dom.spec.whatwg.org/#slot-assigned-nodes

manually_assigned_nodes: RefCell<Vec<Slottable>>

https://html.spec.whatwg.org/multipage/#manually-assigned-nodes

is_in_agents_signal_slots: Cell<bool>

Whether there is a queued signal change for this element

Necessary to avoid triggering too many slotchange events

Implementations

impl HTMLSlotElement

fn __assert_parent_type(&self)

impl HTMLSlotElement

fn new_inherited( local_name: LocalName, prefix: Option<Prefix>, document: &Document, ) -> HTMLSlotElement

pub(crate) fn new( local_name: LocalName, prefix: Option<Prefix>, document: &Document, proto: Option<HandleObject<'_>>, can_gc: CanGc, ) -> DomRoot<HTMLSlotElement>

pub(crate) fn has_assigned_nodes(&self) -> bool

fn find_flattened_slottables(&self, result: &mut RootedVec<'_, Slottable>)

https://dom.spec.whatwg.org/#find-flattened-slotables

fn find_slottables(&self, result: &mut RootedVec<'_, Slottable>)

https://dom.spec.whatwg.org/#find-slotables

To avoid rooting shenanigans, this writes the returned slottables into the result argument

pub(crate) fn assign_slottables(&self)

https://dom.spec.whatwg.org/#assign-slotables

pub(crate) fn signal_a_slot_change(&self)

https://dom.spec.whatwg.org/#signal-a-slot-change

pub(crate) fn remove_from_signal_slots(&self)

pub(crate) fn assigned_nodes(&self) -> Ref<'_, [Slottable]>

Returns the slot’s assigned nodes if the root’s slot assignment mode is “named”, or the manually assigned nodes otherwise

Trait Implementations

impl Castable for HTMLSlotElement

fn is<T>(&self) -> bool

where T: DerivedFrom<Self>,

Check whether a DOM object implements one of its deriving interfaces.

fn upcast<T>(&self) -> &T

where T: Castable, Self: DerivedFrom<T>,

Cast a DOM object upwards to one of the interfaces it derives from.

fn downcast<T>(&self) -> Option<&T>

where T: DerivedFrom<Self>,

Cast a DOM object downwards to one of the interfaces it might implement.

impl DomObject for HTMLSlotElement

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

impl DomObjectWrap<DomTypeHolder> for HTMLSlotElement

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Option<HandleObject<'_>>, _: Box<Self>, _: CanGc) -> Root<Dom<Self>> = {dom::bindings::codegen::GenericBindings::HTMLSlotElementBinding::HTMLSlotElement_Binding::Wrap::<dom::bindings::codegen::DomTypeHolder::DomTypeHolder> as for<'a, 'b> unsafe fn(script_bindings::script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::option::Option<js::rust::Handle<'b, *mut js::jsapi::JSObject>>, std::boxed::Box<dom::htmlslotelement::HTMLSlotElement>, script_bindings::script_runtime::CanGc) -> script_bindings::root::Root<script_bindings::root::Dom<dom::htmlslotelement::HTMLSlotElement>>}

Function pointer to the general wrap function type

impl HTMLSlotElementMethods<DomTypeHolder> for HTMLSlotElement

fn AssignedNodes(&self, options: &AssignedNodesOptions) -> Vec<DomRoot<Node>>

https://html.spec.whatwg.org/multipage/#dom-slot-assignednodes

fn AssignedElements( &self, options: &AssignedNodesOptions, ) -> Vec<DomRoot<Element>>

https://html.spec.whatwg.org/multipage/#dom-slot-assignedelements

fn Assign(&self, nodes: Vec<ElementOrText<DomTypeHolder>>)

https://html.spec.whatwg.org/multipage/#dom-slot-assign

fn Name(&self) -> DOMString

fn SetName(&self, value: DOMString)

impl HasParent for HTMLSlotElement

fn as_parent(&self) -> &HTMLElement

This is used in a type assertion to ensure that the source and webidls agree as to what the parent type is

type Parent = HTMLElement

impl IDLInterface for HTMLSlotElement

fn derives(class: &'static DOMClass) -> bool

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for HTMLSlotElement

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl MutDomObject for HTMLSlotElement

unsafe fn init_reflector(&self, obj: *mut JSObject)

Initializes the Reflector

impl PartialEq for HTMLSlotElement

fn eq(&self, other: &Self) -> 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 ToJSValConvertible for HTMLSlotElement

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandleValue<'_>)

Convert self to a JSVal. JSAPI failure causes a panic.

impl Traceable for HTMLSlotElement

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.

impl VirtualMethods for HTMLSlotElement

fn attribute_mutated(&self, attr: &Attr, mutation: AttributeMutation<'_>)

https://dom.spec.whatwg.org/#shadow-tree-slots

fn super_type(&self) -> Option<&dyn VirtualMethods>

Returns self as the superclass of the implementation for this trait, if any.

fn bind_to_tree(&self, context: &BindContext)

Called when a Node is appended to a tree, where ‘tree_connected’ indicates whether the tree is part of a Document.

fn unbind_from_tree(&self, context: &UnbindContext<'_>)

Called when a Node is removed from a tree, where ‘tree_connected’ indicates whether the tree is part of a Document. Implements removing steps: https://dom.spec.whatwg.org/#concept-node-remove-ext

fn attribute_affects_presentational_hints(&self, attr: &Attr) -> bool

Returns true if given attribute attr affects style of the given element.

fn parse_plain_attribute(&self, name: &LocalName, value: DOMString) -> AttrValue

Returns the right AttrValue variant for the attribute with name name on this element.

fn post_connection_steps(&self)

Invoked during a DOM tree mutation after a node becomes connected, once all related DOM tree mutations have been applied. https://dom.spec.whatwg.org/#concept-node-post-connection-ext

fn children_changed(&self, mutation: &ChildrenMutation<'_>)

Called on the parent when its children are changed.

fn handle_event(&self, event: &Event)

Called during event dispatch after the bubbling phase completes.

fn adopting_steps(&self, old_doc: &Document)

https://dom.spec.whatwg.org/#concept-node-adopt-ext

fn cloning_steps( &self, copy: &Node, maybe_doc: Option<&Document>, clone_children: CloneChildrenFlag, )

https://dom.spec.whatwg.org/#concept-node-clone-ext

fn pop(&self)

Called on an element when it is popped off the stack of open elements of a parser.
