Configuration for a P2P node

Fields

peer_id: Option<PeerId>

Local peer ID for this node

listen_addrs: Vec<SocketAddr>

Addresses to listen on for incoming connections

listen_addr: SocketAddr

Primary listen address (for compatibility)

bootstrap_peers: Vec<SocketAddr>

Bootstrap peers to connect to on startup (legacy)

bootstrap_peers_str: Vec<String>

Bootstrap peers as strings (for integration tests)

enable_ipv6: bool

Enable IPv6 support

connection_timeout: Duration

Connection timeout duration

keep_alive_interval: Duration

Keep-alive interval for connections

max_connections: usize

Maximum number of concurrent connections

max_incoming_connections: usize

Maximum number of incoming connections

dht_config: DHTConfig

DHT configuration

security_config: SecurityConfig

Security configuration

production_config: Option<ProductionConfig>

Production hardening configuration

bootstrap_cache_config: Option<CacheConfig>

Bootstrap cache configuration

diversity_config: Option<IPDiversityConfig>

Optional IP diversity configuration for Sybil protection tuning.

When set, this configuration is used by bootstrap peer discovery and other diversity-enforcing subsystems. If None, defaults are used.

stale_peer_threshold: Duration

Stale peer threshold - peers with no activity for this duration are considered stale. Defaults to 60 seconds. Can be reduced for testing purposes.

max_message_size: Option<usize>

Optional override for the maximum application-layer message size.

When None, the transport crate default is used (1 MiB).
