RelayTunnel

dig_nat::relay

Struct RelayTunnel 

Source 
pub struct RelayTunnel { /* private fields */ }
Expand description

A live RLY-002 relayed-transport tunnel to one peer, multiplexed over the node’s persistent relay reservation socket (the tier-6 TURN fallback). Writes are framed as RLY-002 relay_message to the target and forwarded A→relay→B; reads are the payloads the relay forwards back from that peer.

Per NC-1 the payload MUST be END-TO-END SEALED to the recipient’s key by the caller — the relay is an untrusted forwarder that sees only ciphertext. Dropping the tunnel deregisters its routing.

Implementations§

Source§

impl RelayTunnel

Source

pub fn target(&self) -> &str

The remote peer this tunnel forwards to/from (hex peer_id).

Source

pub fn network_id(&self) -> &str

The network the tunnel is scoped to.

Source

pub fn send(&self, payload: Vec<u8>) -> Result<(), String>

Send payload to the target peer through the relay (RLY-002 relay_message). payload MUST already be sealed to the recipient (NC-1). Err if the reservation dropped (send after the session closed) or payload exceeds MAX_RELAY_PAYLOAD.

Source

pub async fn recv(&mut self) -> Option<Vec<u8>>

Await the next payload the relay forwards from the target peer. None once the reservation drops (the session closed) — the caller should re-open the tunnel after the relay reconnects.
