ruma-events notes



  • There is a hierarchy of event traits: Event > RoomEvent > StateEvent
  • There is a Rust type for each kind of event (each allowed value for the 'type' field of the json representation), including custom [room / state] events
  • There is also a content type for each event type
  • In addition, there are "special" event types:
  • the Event, RoomEvent and StateEvent enums from collections::all contain every event type
