std::net::IpAddr

Enum std::net::IpAddr

pub enum IpAddr {
    V4(Ipv4Addr),
    V6(Ipv6Addr),
}

An IP address, either IPv4 or IPv6.

This enum can contain either an Ipv4Addr or an Ipv6Addr, see their respective documentation for more details.

Examples

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

let localhost_v4 = IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1));
let localhost_v6 = IpAddr::V6(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1));

assert_eq!("127.0.0.1".parse(), Ok(localhost_v4));
assert_eq!("::1".parse(), Ok(localhost_v6));

assert_eq!(localhost_v4.is_ipv6(), false);
assert_eq!(localhost_v4.is_ipv4(), true);

Variants

An IPv4 address.

An IPv6 address.

Methods

impl IpAddr [src]

Returns true for the special 'unspecified' address.

See the documentation for Ipv4Addr::is_unspecified and Ipv6Addr::is_unspecified for more details.

Examples

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

assert_eq!(IpAddr::V4(Ipv4Addr::new(0, 0, 0, 0)).is_unspecified(), true);
assert_eq!(IpAddr::V6(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0)).is_unspecified(), true);

Returns true if this is a loopback address.

See the documentation for Ipv4Addr::is_loopback and Ipv6Addr::is_loopback for more details.

Examples

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

assert_eq!(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)).is_loopback(), true);
assert_eq!(IpAddr::V6(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0x1)).is_loopback(), true);

???? This is a nightly-only experimental API. (ip #27709)extra functionality has not been scrutinized to the level that it should be stable

Returns true if the address appears to be globally routable.

See the documentation for Ipv4Addr::is_global and Ipv6Addr::is_global for more details.

Examples

#![feature(ip)]

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

fn main() {
    assert_eq!(IpAddr::V4(Ipv4Addr::new(80, 9, 12, 3)).is_global(), true);
    assert_eq!(IpAddr::V6(Ipv6Addr::new(0, 0, 0x1c9, 0, 0, 0xafc8, 0, 0x1)).is_global(),
               true);
}

Returns true if this is a multicast address.

See the documentation for Ipv4Addr::is_multicast and Ipv6Addr::is_multicast for more details.

Examples

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

assert_eq!(IpAddr::V4(Ipv4Addr::new(224, 254, 0, 0)).is_multicast(), true);
assert_eq!(IpAddr::V6(Ipv6Addr::new(0xff00, 0, 0, 0, 0, 0, 0, 0)).is_multicast(), true);

???? This is a nightly-only experimental API. (ip #27709)extra functionality has not been scrutinized to the level that it should be stable

Returns true if this address is in a range designated for documentation.

See the documentation for Ipv4Addr::is_documentation and Ipv6Addr::is_documentation for more details.

Examples

#![feature(ip)]

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

fn main() {
    assert_eq!(IpAddr::V4(Ipv4Addr::new(203, 0, 113, 6)).is_documentation(), true);
    assert_eq!(IpAddr::V6(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0))
                      .is_documentation(), true);
}

Returns true if this address is an IPv4 address, and false otherwise.

Examples

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

fn main() {
    assert_eq!(IpAddr::V4(Ipv4Addr::new(203, 0, 113, 6)).is_ipv4(), true);
    assert_eq!(IpAddr::V6(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0)).is_ipv4(),
               false);
}

Returns true if this address is an IPv6 address, and false otherwise.

Examples

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

fn main() {
    assert_eq!(IpAddr::V4(Ipv4Addr::new(203, 0, 113, 6)).is_ipv6(), false);
    assert_eq!(IpAddr::V6(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0)).is_ipv6(),
               true);
}
