Enum ipnet::IpNet[−][src]

pub enum IpNet {
    V4(Ipv4Net),
    V6(Ipv6Net),
}

Expand description

An IP network address, either IPv4 or IPv6.

This enum can contain either an Ipv4Net or an Ipv6Net. A From implementation is provided to convert these into an IpNet.

Textual representation

IpNet provides a FromStr implementation for parsing network addresses represented in CIDR notation. See IETF RFC 4632 for the CIDR notation.

Examples

use std::net::IpAddr;
use ipnet::IpNet;

let net: IpNet = "10.1.1.0/24".parse().unwrap();
assert_eq!(Ok(net.network()), "10.1.1.0".parse());

let net: IpNet = "fd00::/32".parse().unwrap();
assert_eq!(Ok(net.network()), "fd00::".parse());

Variants

V4(Ipv4Net)

V6(Ipv6Net)
