Configuration for the DHT.

Fields

bind_addr: SocketAddr

Address to bind the UDP socket.

bootstrap_nodes: Vec<String>

Bootstrap nodes (host:port strings resolved at startup).

own_id: Option<Id20>

Our node ID. Generated randomly if None.

queries_per_second: usize

Max outgoing queries per second (0 = unlimited).

query_timeout: Duration

Timeout for individual KRPC queries.

address_family: AddressFamily

Address family for this DHT instance (determines compact format and DNS filtering).

enforce_node_id: bool

BEP 42: Enforce node ID verification when inserting into routing table. Nodes with IDs that don’t match their IP are rejected.

restrict_routing_ips: bool

BEP 42: Restrict routing table to one node per IP address.

dht_max_items: usize

BEP 44: Maximum number of stored DHT items (immutable + mutable).

dht_item_lifetime_secs: u64

BEP 44: Lifetime of DHT items in seconds before expiry.

max_routing_nodes: usize

Maximum number of nodes in the routing table. Prevents unbounded growth from adversarial node injection. Default: 512 (matches rqbit).

state_dir: Option<PathBuf>

Directory for persisting DHT routing table state as JSON. When set, the actor saves/loads dht_state.json (V4) or dht_state_v6.json (V6) via atomic temp-file + rename.

read_only_mode: bool

BEP 43: Read-only mode. When enabled, outgoing queries include ro: 1 and the node does not send announce_peer messages. Other nodes should not add us to their routing tables.

enable_multi_address: bool

BEP 45: Include want in outgoing find_node/get_peers to request both IPv4 and IPv6 nodes from dual-stack peers.

Implementations

impl DhtConfig

pub fn default_v6() -> Self

Trait Implementations

impl Clone for DhtConfig

fn clone(&self) -> DhtConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DhtConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DhtConfig

fn default() -> Self

Returns the “default value” for a type.
