Implementations

impl SpaceViewClassRegistry

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

Adds a new space view class.

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

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

Removes a space view class from the registry.

fn get_class( &self, name: SpaceViewClassIdentifier ) -> Option<&dyn SpaceViewClass>

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

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

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

If the class is unknown, returns a placeholder name.

pub fn get_class_or_log_error( &self, name: SpaceViewClassIdentifier ) -> &dyn SpaceViewClass

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

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

Iterates over all registered Space 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, space_view_class_identifier: SpaceViewClassIdentifier ) -> ViewContextCollection

pub fn new_visualizer_collection( &self, space_view_class_identifier: SpaceViewClassIdentifier ) -> VisualizerCollection
