    pub actor_states: HashMap<ActorId, ActorState>,
    pub actor_ids_by_type: HashMap<ObjectId, Vec<ActorId>>,
}

Fields

actor_states: HashMap<ActorId, ActorState>

A map of actor states with their corresponding actor ids.

actor_ids_by_type: HashMap<ObjectId, Vec<ActorId>>

A map of actor ids with their corresponding object ids.
