pub fn find_parent_scope<COMP: BaseComponent>(&self) -> Option<Scope<COMP>>

Attempts to find a parent scope of a certain type

Returns None if no parent scope with the specified type was found.

pub fn context<T: Clone + PartialEq + 'static>( &self, callback: Callback<T>, ) -> Option<(T, ContextHandle<T>)>

Accesses a value provided by a parent ContextProvider component of the same type.
