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: initial_dns_seedlist_discovery.rs
    path of file: ./repos/mongo-rust-driver/src/test/spec
    
    the code of the file until where you have to start completion: use std::time::{Duration, Instant};

use serde::Deserialize;

use crate::{
    bson::doc,
    client::Client,
    options::{ClientOptions, ResolverConfig},
    test::{get_client_options, log_uncaptured, run_spec_test, TestClient},
};

#[derive(Debug, Deserialize)]
#[serde(deny_unknown_fields)]
struct TestFile 
    
async fn load_balanced() {
    let client = TestClient::new().await;
    if !client.is_load_balanced() {
        log_uncaptured(
            "skipping initial_dns_seedlist_discovery::load_balanced due to unmet topology \
             requirement (not a load balanced cluster)",
        );
        return;
    }
    run_spec_test(
        &["initial-dns-seedlist-discovery", "load-balanced"],
        run_test,
    )
    .await;
}
