Find IP addresses for all Chromecasts on the local network.

```rust extern crate mdns;

use mdns::{Record, RecordKind}; use std::net::IpAddr;

const SERVICENAME: &'static str = "googlecast._tcp.local";

fn main() { for response in mdns::discover::all(SERVICE_NAME).unwrap() { let response = response.unwrap();

    let addr = response.records()
                       .filter_map(self::to_ip_addr)
                       .next();

    if let Some(addr) = addr {
        println!("found cast device at {}", addr);
    } else {
        println!("cast device does not advertise address");
    }
}

}

fn toipaddr(record: &Record) -> Option { match record.kind { RecordKind::A(addr) => Some(addr.into()), RecordKind::AAAA(addr) => Some(addr.into()), _ => None, } } ```
