+/**
+ * A trait indicating an object may generate events.
+ * 
+ * Events are processed by passing an [`EventHandler`] to [`process_pending_events`].
+ * 
+ * Implementations of this trait may also feature an async version of event handling, as shown with
+ * [`ChannelManager::process_pending_events_async`] and
+ * [`ChainMonitor::process_pending_events_async`].
+ * 
+ * # Requirements
+ * 
+ * When using this trait, [`process_pending_events`] will call [`handle_event`] for each pending
+ * event since the last invocation.
+ * 
+ * In order to ensure no [`Event`]s are lost, implementors of this trait will persist [`Event`]s
+ * and replay any unhandled events on startup. An [`Event`] is considered handled when
+ * [`process_pending_events`] returns, thus handlers MUST fully handle [`Event`]s and persist any
+ * relevant changes to disk *before* returning.
+ * 
+ * Further, because an application may crash between an [`Event`] being handled and the
+ * implementor of this trait being re-serialized, [`Event`] handling must be idempotent - in
+ * effect, [`Event`]s may be replayed.
+ * 
+ * Note, handlers may call back into the provider and thus deadlocking must be avoided. Be sure to
+ * consult the provider's documentation on the implication of processing events and how a handler
+ * may safely use the provider (e.g., see [`ChannelManager::process_pending_events`] and
+ * [`ChainMonitor::process_pending_events`]).
+ * 
+ * (C-not implementable) As there is likely no reason for a user to implement this trait on their
+ * own type(s).
+ * 
+ * [`process_pending_events`]: Self::process_pending_events
+ * [`handle_event`]: EventHandler::handle_event
