pub fn server_url() -> Option<String>Expand description
huddle 0.8: optional override for the centralized server (a Tor-onion
relay) WebSocket URL, read from config.toml:
server_url = "ws://<your-onion>.onion:80/ws"Precedence is resolved by the caller (main.rs): the --server CLI
flag wins, then this config value, then the baked-in default onion.
So you can repoint the client at a different relay without recompiling
or retyping a flag every launch. Returns None if absent.
