-
-async fn test() {
-    let master = "master.quakeworld.nu:27000";
-    let timeout = Duration::from_secs(2);
-    match masterstat::server_addresses(&master, timeout).await {
-        Ok(result) => { println!("found {} server addresses", result.len()) },
-        Err(e) => { eprintln!("error: {}", e); }
-    }

-**Get server addresses from multiple master servers** (async, in parallel)
-
-```rust
-use std::time::Duration;
-
-async fn test() {
-    let masters = ["master.quakeworld.nu:27000", "master.quakeservers.net:27000"];
-    let timeout = Duration::from_secs(2);
-    let result = masterstat::server_addresses_from_many(&masters, timeout).await;
-    println!("found {} server addresses", result.len());
