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: mesh.rs
    path of file: ./repos/rumqtt/benchmarks/clients
    
    the code of the file until where you have to start completion: use rumqttlog::{Config, Router, Sender, RouterInMessage, RouterOutMessage, DataRequest};
use tokio::task;
use std::thread;
use std::path::PathBuf;
use bytes::Bytes;
use rumqttlog::router::Data;

mod common;

#[tokio::main(core_threads = 1)]
async fn main() {
    pretty_env_logger::init();

    let config = Config {
        id: 0,
        dir: PathBuf::from("/tmp/rumqttlog"),
        max_segment_size: 1024 * 1024,
        max_segment_count: 10000,
        routers: None,
    };

    let (router, tx) = Router::new(config);
    let tx_wr

    let (id, this_rx) = common::new_connection("reader", 100, &tx).await;

    let payload_size = 1024;
    let mut total_size = 0;
    let mut offset = 0;
    let mut segment = 0;

    for _ in 0..10 {
        let request = DataRequest {

            size: 10 * 1024,
            tracker_topic_offset: 0,
        };

        let message = (id.to_owned(), RouterInMessage::DataRequest(request));
        tx.send(message).await.unwrap();

        }
    }

    println!("Id = {}, Total size = {}", id, total_size);
