Trait Implementations

impl Clone for AccessibilityNodeState

fn clone(&self) -> AccessibilityNodeState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for AccessibilityNodeState

type Tracking = Untracked

Specify what this storage should track. Can be one of: [track::Untracked], [track::Insertion], [track::Modification], [track::Removal], [track::All].

impl Debug for AccessibilityNodeState

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

Formats the value using the given formatter.

impl Default for AccessibilityNodeState

fn default() -> AccessibilityNodeState

Returns the “default value” for a type.

impl ParseAttribute for AccessibilityNodeState

fn parse_attribute( &mut self, attr: OwnedAttributeView<'_, CustomAttributeValues>, ) -> Result<(), ParseError>

fn parse_safe(&mut self, attr: OwnedAttributeView<'_, CustomAttributeValues>)

impl PartialEq for AccessibilityNodeState

fn eq(&self, other: &AccessibilityNodeState) -> 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 State<CustomAttributeValues> for AccessibilityNodeState

fn create<'a>( node_view: NodeView<'_, CustomAttributeValues>, node: <<AccessibilityNodeState as State<CustomAttributeValues>>::NodeDependencies as Dependancy>::ElementBorrowed<'a>, parent: Option<<<AccessibilityNodeState as State<CustomAttributeValues>>::ParentDependencies as Dependancy>::ElementBorrowed<'a>>, children: Vec<<<AccessibilityNodeState as State<CustomAttributeValues>>::ChildDependencies as Dependancy>::ElementBorrowed<'a>>, context: &SendAnyMap, ) -> AccessibilityNodeState

Create a new instance of this state

type ParentDependencies = ()

This is a tuple of (T: State, ..) of states read from the parent required to update this state

type ChildDependencies = ()

This is a tuple of (T: State, ..) of states read from the children required to update this state

type NodeDependencies = ()

This is a tuple of (T: State, ..) of states read from the node required to update this state

const NODE_MASK: NodeMaskBuilder<'static> = _

This is a mask of what aspects of the node are required to update this state

fn update<'a>( &mut self, node_view: NodeView<'_, CustomAttributeValues>, _node: <<AccessibilityNodeState as State<CustomAttributeValues>>::NodeDependencies as Dependancy>::ElementBorrowed<'a>, _parent: Option<<<AccessibilityNodeState as State<CustomAttributeValues>>::ParentDependencies as Dependancy>::ElementBorrowed<'a>>, _children: Vec<<<AccessibilityNodeState as State<CustomAttributeValues>>::ChildDependencies as Dependancy>::ElementBorrowed<'a>>, context: &SendAnyMap, ) -> bool

Update this state in a node, returns if the state was updated

fn workload_system( type_id: TypeId, dependants: Arc<Dependants>, pass_direction: PassDirection, ) -> WorkloadSystem

Create a workload system for this state

const TRAVERSE_SHADOW_DOM: bool = false

Does the state traverse into the shadow dom or pass over it. This should be true for layout and false for styles

fn allow_node(node_type: &NodeType<V>) -> bool

Filter out types of nodes that don’t need this State

fn to_type_erased() -> TypeErasedState<V>

where Self: Sized,

Converts to a type erased version of the trait
