How to use addr

[xhyrom]

How can i use addr in my project?

pub fn network_interfaces() -> Vec<NetworkInfo> {
    let mut all_network_interfaces = Vec::new();

    for network in network_interface::NetworkInterface::show().unwrap().iter() {
        all_network_interfaces.push(NetworkInfo {
            name: network.name.to_string(),
            address: network.addr.unwrap().ip, // i want to return ip
        })
    }

    all_network_interfaces
}

Hi @xhyrom! Thanks for opening this question.

As I understand, you want to have the Network Interface's name and IP to build a your NetworkInfo instance, I assume the type for address to be an instance of std::net::IpAddr. What do you think about this approach?

use network_interface::{Addr, NetworkInterface, NetworkInterfaceConfig};
use std::net::IpAddr;

struct NetworkInfo {
    name: String,
    addr: IpAddr,
}

fn main() {
    let network_interfaces = NetworkInterface::show().unwrap();
    let ifaces = network_interfaces.iter().filter_map(|netifa| {
        if let Some(netifa_addr) = netifa.addr {
            let addr: IpAddr = match netifa_addr {
                Addr::V4(ip_addr) => IpAddr::V4(ip_addr.ip),
                Addr::V6(ip_addr) => IpAddr::V6(ip_addr.ip),
            };

            return Some(NetworkInfo {
                name: netifa.name.clone(),
                addr,
            });
        }

        None
    }).collect::<Vec<NetworkInfo>>();
}
