A shared handle to a name scope, compared by identity so that it can be a property value.

Tuple Fields

0: Rc<dyn INameScope>

Implementations

impl NameScopeRef

pub fn new(scope: impl INameScope + 'static) -> Self

Methods from Deref<Target = dyn INameScope>

pub fn find_as<T: ObjectType>(&self, name: &str) -> Option<Ref<T>>

Finds a named element in the name scope and casts it to class T.

Returns None if the name is not registered; panics if the element is of a different class.

pub fn get_as<T: ObjectType>(&self, name: &str) -> Ref<T>

Gets a named element from the name scope and casts it to class T.

Panics if the name is not registered or the element is of a different class.
