A state that is automatically inserted in a node with dependencies.

Required Associated Types

type ParentDependencies: Dependancy

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

type ChildDependencies: Dependancy

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

type NodeDependencies: Dependancy

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

Required Associated Constants

const NODE_MASK: NodeMaskBuilder<'static>

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

Provided Associated Constants

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

Required Methods

fn update<'a>( &mut self, node_view: NodeView<'_, V>, node: <Self::NodeDependencies as Dependancy>::ElementBorrowed<'a>, parent: Option<<Self::ParentDependencies as Dependancy>::ElementBorrowed<'a>>, children: Vec<<Self::ChildDependencies as Dependancy>::ElementBorrowed<'a>>, context: &SendAnyMap, ) -> bool

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

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

Create a new instance of this state

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

Create a workload system for this state

Provided Methods

fn to_type_erased() -> TypeErasedState<V>

where Self: Sized,

Converts to a type erased version of the trait
