An Element is an instentation of a Component

Fields

id: String

The id as named in the original .60 file.

Note that it can only be used for lookup before inlining. After inlining there can be duplicated id in the component. The id are then re-assigned unique id in the assign_id pass

base_type: Typebindings: HashMap<String, ExpressionSpanned>

Currently contains also the signals. FIXME: should that be changed?

children: Vec<ElementRc>enclosing_component: Weak<Component>

The component which contains this element.

property_declarations: HashMap<String, PropertyDeclaration>property_animations: HashMap<String, PropertyAnimation>repeated: Option<RepeatedElementInfo>

Tis element is part of a `for in :

states: Vec<State>transitions: Vec<Transition>child_of_layout: bool

true when this item's geometry is handled by a layout

item_index: OnceCell<usize>

This is the component-local index of this item in the item tree array. It is generated after the last pass and before the generators run.

node: Option<Element>

The AST node, if available
