Enum QueryEvent 

pub enum QueryEvent {
    Answer(CollectedAnswer),
    Terminal(QueryUpdate),
}

Per-answer event surfaced on the Query stream.

Variants

Answer(CollectedAnswer)

A new answer collected by the underlying state machine.

The answer stream is lossy under sustained backpressure: if the application drains Query::next slower than answers arrive, the oldest buffered answers are dropped once the per-query backlog fills (see Query::dropped_answers to observe how many). Discovery is eventually-consistent — mDNS responders re-advertise — so a dropped answer is normally re-collected, but a caller must not assume the stream is gap-free.

Terminal(QueryUpdate)

The query reached a terminal state. Always the last event delivered, and never dropped under backpressure.
