Struct CoreEventConfig 

pub struct CoreEventConfig<C: Core> { /* private fields */ }

Event-listener registration for frontend-to-core notifications.

Register listeners from Core::configure_events. The wrapper installs the matching low-level libretro callbacks during environment setup, avoiding call-order bugs where a core defines a callback but forgets to enable the raw callback separately. Listeners are dispatched in registration order. Registering the same callback function more than once for the same event is a no-op, matching DOM addEventListener behavior. Use the matching remove_*_listener method with the same callback function to remove a listener during configuration. Callback-shaped frontend hooks with one active registration, such as frame timing, use explicit set_*_callback and clear_*_callback methods instead.
