Expand description

Information about a running query.

Variants§

§

Bootstrap

A query initiated by Behaviour::bootstrap.

Fields

§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.

§step: ProgressStep

§

GetClosestPeers

A (repeated) query initiated by Behaviour::get_closest_peers.

Fields

§key: Vec<u8>

The key being queried (the preimage).

§step: ProgressStep

Current index of events.

§num_results: NonZero<usize>

Specifies expected number of responding peers

§

GetProviders

A (repeated) query initiated by Behaviour::get_providers.

Fields

§key: Key

The key for which to search for providers.

§providers_found: usize

The number of providers found so far.

§step: ProgressStep

Current index of events.

§

AddProvider

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

Fields

§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 Behaviour::put_record.

Fields

§record: Record

§quorum: NonZero<usize>

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 (repeated) query initiated by Behaviour::get_record.

Fields

§key: Key

The key to look for.

§step: ProgressStep

Current index of events.

§found_a_record: bool

Did we find at least one record?

§cache_candidates: BTreeMap<Distance, PeerId>

The peers closest to the key that were queried but did not return a record, i.e. the peers that are candidates for caching the record.
