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: kademlia.rs
    path of file: ./repos/rust-ipfs/tests
    
    the code of the file until where you have to start completion: use cid::{Cid, Codec};
use ipfs::{p2p::MultiaddrWithPeerId, Block, Node};
use libp2p::{kad::Quorum, multiaddr::Protocol, Multiaddr};
use multihash::Sha2_256;
use tokio::time::timeout;

use std::{convert::TryInto, time::Duration};

mod common;
use common::{interop::ForeignNode, spawn_nodes, Topology};

fn strip_peer_id(addr: Multiaddr) 
    
async fn dht_find_peer() {
    // works for numbers >=2, though 2 would essentially just
    // be the same as find_peer_local, so it should be higher
    const CHAIN_LEN: usize = 10;
    let (nodes, foreign_node) = spawn_bootstrapped_nodes(CHAIN_LEN).await;
    let last_index = CHAIN_LEN - if foreign_node.is_none() { 1 } else { 2 };

    // node 0 now tries to find the address of the very last node in the
    // chain; the chain should be long enough for it not to automatically
    // be connected to it after the bootstrap
    let found_addrs = nodes[0].find_peer(nodes[last_index].id).await.unwrap();

    let to_be_found = strip_peer_id(nodes[last_index].addrs[0].clone());
    assert_eq!(found_addrs, vec![to_be_found]);
}
