Implementations

impl ViewClassRegistry

pub fn add_class<T: ViewClass + Default + 'static>( &mut self, ) -> Result<(), ViewClassRegistryError>

Adds a new view class.

Fails if a view class with the same name was already registered.

pub fn remove_class<T: ViewClass + Sized>( &mut self, ) -> Result<(), ViewClassRegistryError>

Removes a view class from the registry.

fn get_class(&self, name: ViewClassIdentifier) -> Option<&dyn ViewClass>

Queries a View type by class name, returning None if it is not registered.

pub fn display_name(&self, name: ViewClassIdentifier) -> &'static str

Returns the user-facing name for the given view class.

If the class is unknown, returns a placeholder name.

pub fn get_class_or_log_error( &self, name: ViewClassIdentifier, ) -> &dyn ViewClass

Queries a View type by class name and logs if it fails, returning a placeholder class.

pub fn iter_registry(&self) -> impl Iterator<Item = &ViewClassRegistryEntry>

Iterates over all registered View class types, sorted by name.

pub fn applicable_entities_for_visualizer_systems( &self, store_id: &StoreId, ) -> PerVisualizer<ApplicableEntities>

For each visualizer, return the set of entities that is applicable to it.

The list is kept up to date by store subscribers.

pub fn indicated_entities_per_visualizer( &self, store_id: &StoreId, ) -> PerVisualizer<IndicatedEntities>

For each visualizer, the set of entities that have at least one matching indicator component.

pub fn new_context_collection( &self, view_class_identifier: ViewClassIdentifier, ) -> ViewContextCollection

pub fn new_visualizer_collection( &self, view_class_identifier: ViewClassIdentifier, ) -> VisualizerCollection
