Module peer_table 

Unified peer table for both discv4 and discv5 discovery protocols.

This module provides a protocol-agnostic peer table that stores contact information discovered through either discv4 or discv5. The key abstraction is using Bytes for ping identifiers:

• discv4: converts H256 ping hash to Bytes
• discv5: already uses Bytes for req_id

Each contact is tagged with the protocol that discovered it, allowing protocol-specific lookups to only query compatible contacts.

Modules

peer_table_server_protocol

Structs

Contact

KBucket

A single k-bucket in the Kademlia routing table. Each bucket stores contacts at a specific XOR distance range from the local node.

PeerData

PeerDiagnostics

Diagnostic snapshot of a peer’s state, used by admin RPC endpoints.

PeerTableServer

RequestPermit

Reservation handle for a peer request slot.

Enums

ContactValidation

Result of contact validation.

DiscoveryProtocol

Identifies which discovery protocol was used to find a contact. This allows protocol-specific lookups to only query compatible contacts.

Constants

MAX_NODES_PER_BUCKET

Maximum number of contacts per k-bucket (Kademlia k parameter).

TARGET_PEERS

The target number of RLPx connections to reach.
