Expand description

Events generated by DHT as a response to get_value and put_value requests.

Variants§

§

ClosestPeersFound(PeerId, Vec<(PeerId, Vec<Multiaddr>)>)

Found closest peers to the target PeerId. With libp2p also delivers a partial result in case the query timed out, because it can contain the target peer’s address.

§

ClosestPeersNotFound(PeerId)

Closest peers to the target PeerId has not been found.

§

ValueFound(PeerRecord)

The value was found.

§

ValueNotFound(Key)

The requested record has not been found in the DHT.

§

ValuePut(Key)

The record has been successfully inserted into the DHT.

§

ValuePutFailed(Key)

An error has occurred while putting a record into the DHT.

§

StartedProviding(Key)

Successfully started providing the given key.

§

StartProvidingFailed(Key)

An error occured while registering as a content provider on the DHT.

§

PutRecordRequest(Key, Vec<u8>, Option<PeerId>, Option<Instant>)

The DHT received a put record request.

§

ProvidersFound(Key, Vec<PeerId>)

The providers for Key were found. Multiple such events can be generated per provider discovery request.

§

NoMoreProviders(Key)

GET_PROVIDERS query finished and won’t yield any more providers.

§

ProvidersNotFound(Key)

GET_PROVIDERS query failed and no providers for Key were found. libp2p also emits this event after already yielding some results via DhtEvent::ProvidersFound.
