Struct ProxyChainTunnel 

pub struct ProxyChainTunnel { /* private fields */ }

Intercepts all TCP flows arriving on a TUN device and relays them through the configured proxy chain.

Implementations

impl ProxyChainTunnel

pub fn new(config: TunnelConfig) -> Self

Create a new tunnel with the given configuration.

pub fn spawn(self, tun_file: File, rt: Handle) -> JoinHandle<Result<()>>

Spawn the blocking poll loop on a new OS thread and return immediately.

tun_file must be a File wrapping the TUN device fd with O_NONBLOCK set. The returned thread::JoinHandle can be used to detect if the loop exits unexpectedly.

pub async fn run(self, tun_file: File) -> Result<()>

Run the tunnel loop on an async task, blocking the current async context until the tunnel exits.

The blocking work runs on a dedicated OS thread (not the Tokio thread pool) so that the non-Send smoltcp state stays on its own thread.

Errors

Propagates any error returned by the poll loop.
