Information about a running query.

Variants

Bootstrap

A query initiated by Kademlia::bootstrap.

Fields of Bootstrap

peer: PeerId

The targeted peer ID.

remaining: Option<IntoIter<Key<PeerId>>>

The remaining random peer IDs to query, one per bucket that still needs refreshing.

This is None if the initial self-lookup has not yet completed and Some with an exhausted iterator if bootstrapping is complete.

GetClosestPeers

A query initiated by Kademlia::get_closest_peers.

Fields of GetClosestPeers

key: Vec<u8>
GetProviders

A query initiated by Kademlia::get_providers.

Fields of GetProviders

key: Key

The key for which to search for providers.

providers: HashSet<PeerId>

The found providers.

AddProvider

A (repeated) query initiated by Kademlia::start_providing.

Fields of AddProvider

key: Key

The record key.

phase: AddProviderPhase

The current phase of the query.

context: AddProviderContext

The execution context of the query.

PutRecord

A (repeated) query initiated by Kademlia::put_record.

Fields of PutRecord

record: Recordquorum: NonZeroUsize

The expected quorum of responses w.r.t. the replication factor.

phase: PutRecordPhase

The current phase of the query.

context: PutRecordContext

The execution context of the query.

GetRecord

A query initiated by Kademlia::get_record.

Fields of GetRecord

key: Key

The key to look for.

records: Vec<PeerRecord>

The records with the id of the peer that returned them. None when the record was found in the local store.

quorum: NonZeroUsize

The number of records to look for.

cache_at: Option<Key<PeerId>>

The closest peer to key that did not return a record.

When a record is found in a standard Kademlia query (quorum == 1), it is cached at this peer as soon as a record is found.
