RelayHandle

rings_node::extension::protocols::relay

Struct RelayHandle 

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

Client-facing handle to the relay extension’s live engine: open local tunnels and register local services. This is the relay extension’s own surface — the relay owns its engine and installs itself (install), so nothing about it leaks into the generic Provider. Cloneable; every clone drives the same shared engine and pure Relay state. Holds the two per-namespace scoped capabilities (tcp / udp); each method picks one and can only act within it, so the handle cannot address an arbitrary namespace even internally.

Implementations§

Source§

impl RelayHandle

Source

pub fn install(extensions: &Extensions) -> Result<Self>

Install the relay into an extension registry: register the TCP and UDP interpreters over a fresh, relay-owned OS-socket engine and return the client handle. Errors if the tcp/udp namespaces are already taken. Call once per node, after constructing the provider — the relay is opt-in, not a Provider invariant.

Source

pub async fn open_tcp_tunnel( &self, local_addr: SocketAddr, peer: Did, service: String, ) -> Result<()>

Open a local TCP tunnel: bind local_addr and relay each accepted connection to peer’s service (client side, forward proxy).

Source

pub async fn relay_tcp_stream( &self, stream: TcpStream, peer: Did, service: String, ) -> Result<()>

Relay one already-accepted TCP stream to peer’s service.

Source

pub async fn open_udp_tunnel( &self, local_addr: SocketAddr, peer: Did, service: String, ) -> Result<()>

Open a local UDP tunnel: bind local_addr and relay each datagram flow to peer’s service (client side, forward proxy).

Source

pub async fn register_tcp_service( &self, name: String, addr: SocketAddr, ) -> Result<()>

Register (at runtime) a local service the TCP relay may dial (name → addr).

Source

pub async fn register_udp_service( &self, name: String, addr: SocketAddr, ) -> Result<()>

Register (at runtime) a local service the UDP relay may dial (name → addr).
