pub fn lookup_neighbours_expiration(&mut self, duration: Duration) -> &mut Self

Sets the expiration duration for lookup neighbor requests

pub fn bond_expiration(&mut self, duration: Duration) -> &mut Self

Sets the expiration duration for a bond with a peer

pub fn enable_dht_random_walk( &mut self, enable_dht_random_walk: bool, ) -> &mut Self

Whether to discover random nodes in the DHT.

pub fn enable_lookup(&mut self, enable_lookup: bool) -> &mut Self

Whether to automatically lookup

pub fn enable_eip868(&mut self, enable_eip868: bool) -> &mut Self

Whether to enforce expiration timestamps in messages.

pub fn enforce_expiration_timestamps( &mut self, enforce_expiration_timestamps: bool, ) -> &mut Self

Whether to enable EIP-868

pub fn add_eip868_pair( &mut self, key: impl Into<Vec<u8>>, value: impl Encodable, ) -> &mut Self

Add another key value pair to include in the ENR

pub fn add_eip868_rlp_pair( &mut self, key: impl Into<Vec<u8>>, rlp: Bytes, ) -> &mut Self

Add another key value pair to include in the ENR

pub fn extend_eip868_rlp_pairs( &mut self, pairs: impl IntoIterator<Item = (impl Into<Vec<u8>>, Bytes)>, ) -> &mut Self

Extend additional key value pairs to include in the ENR

pub fn ban_list(&mut self, ban_list: BanList) -> &mut Self

A set of lists that can ban IP’s or PeerIds from the server. See [BanList].

pub fn lookup_interval(&mut self, lookup_interval: Duration) -> &mut Self

Sets the lookup interval duration.

pub fn ban_duration(&mut self, ban_duration: Option<Duration>) -> &mut Self

Set the default duration for which nodes are banned for. This timeouts are checked every 5 minutes, so the precision will be to the nearest 5 minutes. If set to None, bans from the filter will last indefinitely. Default is 1 hour.

pub fn add_boot_node(&mut self, node: NodeRecord) -> &mut Self

Adds a boot node

pub fn add_boot_nodes( &mut self, nodes: impl IntoIterator<Item = NodeRecord>, ) -> &mut Self

Adds multiple boot nodes

pub fn external_ip_resolver( &mut self, external_ip_resolver: Option<NatResolver>, ) -> &mut Self

Configures if and how the external IP of the node should be resolved.

pub fn resolve_external_ip_interval( &mut self, resolve_external_ip_interval: Option<Duration>, ) -> &mut Self

Sets the interval at which the external IP is to be resolved.

pub fn build(&self) -> Discv4Config

Returns the configured Discv4Config

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
