Trait Implementations

impl Clone for AccessibilityState

fn clone(&self) -> AccessibilityState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for AccessibilityState

type Tracking = Untracked

Kind of event to track for this component.

impl Debug for AccessibilityState

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

Formats the value using the given formatter.

impl Default for AccessibilityState

fn default() -> AccessibilityState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AccessibilityState

fn deserialize<__D>( __deserializer: __D, ) -> Result<AccessibilityState, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl ParseAttribute for AccessibilityState

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

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

impl PartialEq for AccessibilityState

fn eq(&self, other: &AccessibilityState) -> 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 Serialize for AccessibilityState

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl State<CustomAttributeValues> for AccessibilityState

const NODE_MASK: NodeMaskBuilder<'static>

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

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

Create a new instance of this state

fn update<'a>( &mut self, node_view: NodeView<'_, CustomAttributeValues>, _node: <<AccessibilityState as State<CustomAttributeValues>>::NodeDependencies as Dependancy>::ElementBorrowed<'a>, _parent: Option<<<AccessibilityState as State<CustomAttributeValues>>::ParentDependencies as Dependancy>::ElementBorrowed<'a>>, _children: Vec<<<AccessibilityState 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
