Module libp2p_kad::kbucket

Implementation of a Kademlia routing table as used by a single peer participating in a Kademlia DHT.

The entry point for the API of this module is a KBucketsTable.

Pending Insertions

When the bucket associated with the Key of an inserted entry is full but contains disconnected nodes, it accepts a PendingEntry. Pending entries are inserted lazily when their timeout is found to be expired upon querying the KBucketsTable. When that happens, the KBucketsTable records an AppliedPending result which must be consumed by calling take_applied_pending regularly and / or after performing lookup operations like entry and closest.

Re-exports

pub use super::bucket::K_VALUE;

Structs

AbsentEntry	An entry that is not present in any bucket.
AppliedPending	The result of applying a pending node to a bucket, possibly replacing an existing node.
Distance	A distance between two keys in the DHT keyspace.
EntryRefView	An immutable by-reference view of a bucket entry.
EntryView	A cloned, immutable view of an entry that is either present in a bucket or pending insertion.
KBucketRef	A reference to a bucket in a KBucketsTable.
KBucketsTable	A KBucketsTable represents a Kademlia routing table.
Key	A Key in the DHT keyspace with preserved preimage.
KeyBytes	The raw bytes of a key in the DHT keyspace.
Node	A Node in a bucket, representing a peer participating in the Kademlia DHT together with an associated value (e.g. contact information).
NodeRefView	An immutable by-reference view of a Node.
PendingEntry	An entry waiting for a slot to be available in a bucket.
PresentEntry	An entry present in a bucket.

Enums
