Struct TcpConfig 

pub struct TcpConfig {
    pub bind_addr: Option<String>,
    pub mtu: Option<u16>,
    pub connect_timeout_ms: Option<u64>,
    pub nodelay: Option<bool>,
    pub keepalive_secs: Option<u64>,
    pub recv_buf_size: Option<usize>,
    pub send_buf_size: Option<usize>,
    pub max_inbound_connections: Option<usize>,
    pub advertise_on_nostr: Option<bool>,
    pub external_addr: Option<String>,
}

TCP transport instance configuration.

Fields

bind_addr: Option<String>

Listen address (e.g., “0.0.0.0:443”). If not set, outbound-only.

mtu: Option<u16>

Default MTU for TCP connections. Defaults to 1400. Per-connection MTU is derived from TCP_MAXSEG when available.

connect_timeout_ms: Option<u64>

Outbound connect timeout in milliseconds. Defaults to 5000.

nodelay: Option<bool>

Enable TCP_NODELAY (disable Nagle). Defaults to true.

keepalive_secs: Option<u64>

TCP keepalive interval in seconds. 0 = disabled. Defaults to 30.

recv_buf_size: Option<usize>

TCP receive buffer size in bytes. Defaults to 2 MB.

send_buf_size: Option<usize>

TCP send buffer size in bytes. Defaults to 2 MB.

max_inbound_connections: Option<usize>

Maximum simultaneous inbound connections. Defaults to 256.

advertise_on_nostr: Option<bool>

Whether this transport should be advertised on Nostr overlay discovery. Default: false.

external_addr: Option<String>

Optional explicit public address to advertise. Required when bind_addr is wildcard (e.g. "0.0.0.0:443") and advertise_on_nostr: true, since TCP has no STUN equivalent for autodiscovery. Accepts either a bare IP ("198.51.100.1" — the configured bind_addr port is appended) or a full host:port. Common pattern on AWS EIP / cloud 1:1 NAT setups where the public IP isn’t bindable on the host.

Implementations

impl TcpConfig

pub fn mtu(&self) -> u16

Get the default MTU.

pub fn connect_timeout_ms(&self) -> u64

Get the connect timeout in milliseconds.

pub fn nodelay(&self) -> bool

Whether TCP_NODELAY is enabled. Default: true.

pub fn keepalive_secs(&self) -> u64

Get the keepalive interval in seconds. 0 = disabled. Default: 30.

pub fn recv_buf_size(&self) -> usize

Get the receive buffer size. Default: 2 MB.

pub fn send_buf_size(&self) -> usize

Get the send buffer size. Default: 2 MB.

pub fn max_inbound_connections(&self) -> usize

Get the maximum number of inbound connections. Default: 256.

pub fn advertise_on_nostr(&self) -> bool

Whether this TCP transport should be advertised on Nostr discovery.

pub fn external_advert_addr(&self) -> Option<SocketAddr>

Parse external_addr against the configured bind_addr port, returning the absolute SocketAddr to advertise on Nostr. Returns None if external_addr is unset or malformed, or if bind_addr is unset / unparseable so no port can be inferred.

Trait Implementations

impl Clone for TcpConfig

fn clone(&self) -> TcpConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TcpConfig

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

Formats the value using the given formatter.

impl Default for TcpConfig

fn default() -> TcpConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TcpConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for TcpConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
