Static Public Attributes
static std::unordered_map< std::type_index, EventInfo >	event_data
	Dispatch table keyed by event type; one entry per registered event type.
static std::shared_mutex	registration_mutex
	Guards event_data and unsubscribe_map.
static std::mutex	pool_mutex
	Protects the event queue memory pool during concurrent sends.
static std::unordered_map< std::type_index, std::function< void(std::any)> >	unsubscribe_map
	Type-erased unsubscribe functions keyed by event type; used by Listener to erase iterators without the concrete type.
static std::vector< std::unique_ptr< void, void(*)(void *)> >	deletion_queue
static std::mutex	deletion_mutex
	Protects the event queue memory pool during concurrent sends.

Detailed Description

Internal dispatch table for the event system.

One EventInfo entry exists per registered event type. Do not use this struct directly; go through Listener::subscribe() to register callbacks and event::send() to enqueue events.

Member Data Documentation

deletion_queue

std::vector< std::unique_ptr< void, void(*)(void *)> > event::EventSystem::deletion_queue

static

Deferred-delete queue; callbacks that unsubscribed during pollEvents are freed here on the next call to avoid invalidating the processing vector mid-dispatch
