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: node.rs
    path of file: ./repos/CYFS/src/component/cyfs-bdt/src/dht
    
    the code of the file until where you have to start completion: use super::k_bucket::*;
use crate::protocol::v0::*;
use async_std;
use async
    
    fn handle_response(&mut self, request: NodeRequest, reply: NodeReply) {
        match reply {
            NodeReply::Find(resp) => {
                if let NodeRequest::Find(find_type) = request {
                    let (session, _) = self.get_find_session(&find_type, false);
                    if session.is_none() {
                        return;
                    }

                    let session = session.unwrap();
                    let sender = session.sender.lock().unwrap().clone();
                    if sender.is_none() {
                        return;
                    }
                    let _ = sender.unwrap().send(resp);
                }
            }
        }
    }
