T8b949e//! RNS SOCKS5 client -- local SOCKS5 server that tunnels through RNS.
T8b949e//!
T8b949e//! Equivalent of `rns_socks_client.py`.
T8b949e//!
T8b949e//! The client:
T8b949e//! 1. Starts an RNS node, waits for a path to the server destination.
T8b949e//! 2. Creates an RNS link to the server.
T8b949e//! 3. Listens on a local TCP port for SOCKS5 connections.
T8b949e//! 4. For each SOCKS5 CONNECT, sends a CONNECT frame through the mux and
T8b949e//! relays data bidirectionally.
T8b949e//! 5. Automatically reconnects when the link is lost.
T8b949e//!
T8b949e//! SOCKS5 protocol handling is delegated to `fast-socks5`.
