Struct P2pConfig 

pub struct P2pConfig {
    pub bind_addr: Option<SocketAddr>,
    pub known_peers: Vec<SocketAddr>,
    pub max_connections: usize,
    pub auth: AuthConfig,

    pub stats_interval: Duration,
}

Configuration for ant-quic P2P endpoints

This struct provides all configuration options for P2P networking including NAT traversal, authentication, MTU settings, and post-quantum cryptography.

Named P2pConfig to avoid collision with the low-level config::EndpointConfig which is used for QUIC protocol settings.

Pure P2P Design (v0.13.0+)

All nodes are symmetric - they can connect, accept connections, and coordinate NAT traversal for peers. There is no role distinction.

Fields

bind_addr: Option<SocketAddr>

Local address to bind to. If None, an ephemeral port is auto-assigned with enhanced security through port randomization.

known_peers: Vec<SocketAddr>

Known peers for initial discovery and NAT traversal coordination These can be any nodes in the network - all nodes are symmetric.

max_connections: usize

Maximum number of concurrent connections

auth: AuthConfig

Authentication configuration

nat: NatConfig

NAT traversal configuration

timeouts: TimeoutConfig

Timeout configuration for all operations

pqc: PqcConfig

Post-quantum cryptography configuration

mtu: MtuConfig

MTU configuration for network packet sizing

stats_interval: Duration

Interval for collecting and reporting statistics

Implementations

impl P2pConfig

pub fn builder() -> P2pConfigBuilder

Create a new configuration builder

pub fn to_nat_config(&self) -> NatTraversalConfig

Convert to NatTraversalConfig for internal use

pub fn to_nat_config_with_key( &self, identity_key: SigningKey, ) -> NatTraversalConfig

Convert to NatTraversalConfig with a specific identity key

This ensures the same Ed25519 keypair is used for both P2pEndpoint authentication and TLS/RPK identity in NatTraversalEndpoint.

Trait Implementations

impl Clone for P2pConfig

fn clone(&self) -> P2pConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for P2pConfig

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

Formats the value using the given formatter.

impl Default for P2pConfig

fn default() -> Self

Returns the “default value” for a type.
