inline virtual std::shared_ptr<void> take_data() override: Take data so that the callback cannot be scheduled again.

inline virtual std::shared_ptr<void> take_data_by_entity_id(size_t id) override

Take the data so that it can be consumed with execute.

This function allows to specify an entity ID to take the data from. Entity IDs are identifiers that can be defined by waitable-derived classes that are composed of several distinct entities. The main use-case is in conjunction with the listener APIs.
