Function list_afinet_netifas

Source 
pub fn list_afinet_netifas() -> Result<Vec<(String, IpAddr)>, Error>
Expand description

Perform a search over the system’s network interfaces using getifaddrs, retrieved network interfaces belonging to both socket address families AF_INET and AF_INET6 are retrieved along with the interface address name.

§Example

use std::net::IpAddr;
use local_ip_address::list_afinet_netifas;

let ifas = list_afinet_netifas().unwrap();

if let Some((_, ipaddr)) = ifas
.iter()
.find(|(name, ipaddr)| (*name == "en0" || *name == "epair0b") && matches!(ipaddr, IpAddr::V4(_))) {
    // This is your local IP address: 192.168.1.111
    println!("This is your local IP address: {:?}", ipaddr);
}
