Network.LibP2P.DHT.Types

Description

Core types for the Kademlia DHT.

Defines the DHT keyspace (256-bit SHA-256 keys), routing table entry structure, and protocol constants (k=20, alpha=10).

Synopsis

Documentation

256-bit key in the DHT keyspace (always exactly 32 bytes, SHA-256 output).

Result of attempting to insert a peer into the routing table.

Constructors

Inserted	Peer was added to the bucket
Updated	Existing peer was moved to tail (most recently seen)
BucketFull !PeerId	Bucket is full; returns LRS peer ID for pinging

Replication parameter: each k-bucket holds up to k peers.

Concurrency parameter for iterative lookups.

Number of buckets (one per bit of the 256-bit keyspace).
