You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: routernxn.rs
    path of file: ./repos/rumqtt/benchmarks/router
    
    the code of the file until where you have to start completion: // use argh::FromArgs;
// use rumqttlog::tracker::Tracker;
// use rumqttlog::{Config, Router, RouterInMessage, RouterOutMessage, Sender};
// us
    
// async fn main() {
//     pretty_env_logger::init();
//     let commandline: CommandLine = argh::from_env();
//
//     let config = Config {
//         id: 0,
//         dir: Default::default(),
//         max_segment_size: commandline.segment_size,
//         max_segment_count: 10000,
//         max_connections: 100,
//         mesh: None,
//     };
//
//     let (router, tx) = Router::new(Arc::new(config));
//     thread::spawn(move || start_router(router));
//
//     let (network_tx, network_rx) = bounded(100);
//
//     // start connection
//     let router_tx = tx.clone();
//     let cli = commandline.clone();
//     task::spawn(async move {
//         connection(cli, "connection-1", network_rx, router_tx).await;
//     });
//
//     // start network publisher
//     let cli = commandline.clone();
//     task::spawn(async move {
//         let network_tx = network_tx;
//         for i in 0..cli.message_count {
//             let payload = vec![i as u8; cli.payload_size];
//             let mut packet = Publish::new("hello/mqtt", QoS::AtLeastOnce, payload);
//             packet.set_pkid((i % 65000) as u16 + 1);
//             network_tx.send(packet).await.unwrap();
//         }
