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: client_conn.rs
    path of file: ./repos/iroh/iroh-net/src/derp
    
    the code of the file until where you have to start completion: use std::sync::atomic::{AtomicBool, Ordering};
use std::sync::Arc;
use std::time::Duration;

use anyhow::{ensure, Context, Result
    
    async fn request_mesh_update(&self, updates: Vec<PeerConnState>) -> Result<()> {
        ensure!(
            self.can_mesh,
            "unexpected request to update mesh peers on a connection that is not able to mesh"
        );
        self.mesh_update_s.send(updates).await?;
        Ok(())
    }
