A component is a type in the language which can be instantiated, Or is materialized for repeated expression.

Fields

id: String

root_element: ElementRc

parent_element: Weak<RefCell<Element>>

The parent element within the parent component if this component represents a repeated element

optimized_elements: RefCell<Vec<ElementRc>>

List of elements that are not attached to the root anymore because they have been optimized away, but their properties may still be in use

embedded_file_resources: RefCell<HashMap<String, usize>>

Map of resources that should be embedded in the generated code, indexed by their absolute path on disk on the build system and valued by a unique integer id, that can be used by the generator for symbol generation.

root_constraints: RefCell<LayoutConstraints>

The layout constraints of the root item

child_insertion_point: RefCell<Option<(ElementRc, ChildrenPlaceholder)>>

When creating this component and inserting “children”, append them to the children of the element pointer to by this field.

setup_code: RefCell<Vec<Expression>>

Code to be inserted into the constructor

used_global: RefCell<Vec<Rc<Component>>>

All the globals used by this component and its children. FIXME: can we have cycle?

used_structs: RefCell<Vec<Type>>

popup_windows: RefCell<Vec<PopupWindow>>

Implementations

impl Component

    tr: &TypeRegister
) -> Rc<Self>

pub fn is_global(&self) -> bool

This component is a global component introduced with the “global” keyword

Trait Implementations
