Module matrix_sdk::event_handler
source · [−]Expand description
Types and traits related for event handlers. For usage, see
Client::register_event_handler.
How it works
The register_event_handler method registers event handlers of different
signatures by actually storing boxed closures that all have the same
signature of async (EventHandlerData) -> () where EventHandlerData is a
private type that contains all of the data an event handler might need.
The stored closure takes care of deserializing the event which the
EventHandlerData contains as a (borrowed) serde_json::value::RawValue,
extracting the context arguments from other fields of EventHandlerData and
calling / .awaiting the event handler if the previous steps succeeded.
It also logs any errors from the above chain of function calls.
For more details, see the EventHandler trait.
