let iw = IW::new().await.unwrap();

let mut list = iw.interface_list().await.expect("no nic");
for card in &list {
    println!("ifname: {}", card);
}

let interface = list.remove(0);

println!("scan ...");
let mut ap_list = iw.scan(&interface).await.unwrap();
if let Some(ssid) = args.ssid {
    ap_list.retain(|one| one.ssid.contains(&ssid));
}
for one in ap_list {
    println!("{}", one);
}
```
