| DebugFilter | Filter which matches Debug events, if they satisfy the given criteria:
 
 source, if given, applies a filter on the event’s originmessageapplies a filter on the event’s message (either with String.startsWith or Regex.findFirstIn().isDefined)
 
 If you want to match all Debug events, the most efficient is to useLeft(""). |

| ErrorFilter | Filter which matches Error events, if they satisfy the given criteria:
 
 throwableapplies an upper bound on the type of exception contained in the Error eventsource, if given, applies a filter on the event’s originmessageapplies a filter on the event’s message (either
   with String.startsWith or Regex.findFirstIn().isDefined); if the message
   itself does not match, the match is retried with the contained Exception’s
   message; if both arenull, the filter always matches if at
   the same time the Exception’s stack trace is empty (this catches
   JVM-omitted “fast-throw” exceptions)
 
 If you want to match all Error events, the most efficient is to useLeft(""). |
