Function local_ip_address::linux::list_afinet_netifas

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

Perform a search over the system’s network interfaces using Netlink Route information, 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" && matches!(ipaddr, IpAddr::V4(_))) {
    // This is your local IP address: 192.168.1.111
    println!("This is your local IP address: {:?}", ipaddr);
}
