Expand description

Parameters for configuring the network more granularity via CLI

Fields§

§discovery: DiscoveryArgs

Arguments to setup discovery service.

§trusted_peers: Vec<TrustedPeer>

Comma separated enode URLs of trusted peers for P2P connections.

–trusted-peers enode://abcd@192.168.0.1:30303

§trusted_only: bool

Connect to or accept from trusted peers only

§bootnodes: Option<Vec<TrustedPeer>>

Comma separated enode URLs for P2P discovery bootstrap.

Will fall back to a network-specific default if not specified.

§dns_retries: usize

Amount of DNS resolution requests retries to perform when peering.

§peers_file: Option<PathBuf>

The path to the known peers file. Connected peers are dumped to this file on nodes shutdown, and read on startup. Cannot be used with --no-persist-peers.

§identity: String

Custom node identity

§p2p_secret_key: Option<PathBuf>

Secret key to use for this node.

This will also deterministically set the peer ID. If not specified, it will be set in the data dir for the chain being used.

§no_persist_peers: bool

Do not persist peers.

§nat: NatResolver

NAT resolution method (any|none|upnp|publicip|extip:<IP>)

§addr: IpAddr

Network listening address

§port: u16

Network listening port

§max_outbound_peers: Option<usize>

Maximum number of outbound requests. default: 100

§max_inbound_peers: Option<usize>

Maximum number of inbound requests. default: 30

§max_concurrent_tx_requests: u32

Max concurrent GetPooledTransactions requests.

§max_concurrent_tx_requests_per_peer: u8

Max concurrent GetPooledTransactions requests per peer.

§max_seen_tx_history: u32

Max number of seen transactions to remember per peer.

Default is 320 transaction hashes.

§max_pending_pool_imports: usize

Max number of transactions to import concurrently.

§soft_limit_byte_size_pooled_transactions_response: usize

Experimental, for usage in research. Sets the max accumulated byte size of transactions to pack in one response. Spec’d at 2MiB.

§soft_limit_byte_size_pooled_transactions_response_on_pack_request: usize

Experimental, for usage in research. Sets the max accumulated byte size of transactions to request in one request.

Since RLPx protocol version 68, the byte size of a transaction is shared as metadata in a transaction announcement (see RLPx specs). This allows a node to request a specific size response.

By default, nodes request only 128 KiB worth of transactions, but should a peer request more, up to 2 MiB, a node will answer with more than 128 KiB.

Default is 128 KiB.

§max_capacity_cache_txns_pending_fetch: u32

Max capacity of cache of hashes for transactions pending fetch.

§net_if: Option<String>

Name of network interface used to communicate with peers.

If flag is set, but no value is passed, the default interface for docker eth0 is tried.

Implementations§

Source§

impl NetworkArgs

Source

pub fn resolved_addr(&self) -> IpAddr

Returns the resolved IP address.

Source

pub fn resolved_bootnodes(&self) -> Option<Vec<NodeRecord>>

  1. –bootnodes flag

§

fn quirk(&self, value: Quirk) -> Painted<&T>
