Struct std::net::Ipv6Addr

pub struct Ipv6Addr { /* fields omitted */ }

An IPv6 address.

IPv6 addresses are defined as 128-bit integers in IETF RFC 4291. They are usually represented as eight 16-bit segments.

See IpAddr for a type encompassing both IPv4 and IPv6 addresses.

Textual representation

Ipv6Addr provides a FromStr implementation. There are many ways to represent an IPv6 address in text, but in general, each segments is written in hexadecimal notation, and segments are separated by :. For more information, see IETF RFC 5952.

Examples

use std::net::Ipv6Addr;

let localhost = Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1);
assert_eq!("::1".parse(), Ok(localhost));
assert_eq!(localhost.is_loopback(), true);

Methods

impl Ipv6Addr [src]

[src]

Creates a new IPv6 address from eight 16-bit segments.

The result will represent the IP address a:b:c:d:e:f:g:h.

Examples

use std::net::Ipv6Addr;

let addr = Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff);

[src]

🔬 This is a nightly-only experimental API. (ip_constructors #44582)requires greater scrutiny before stabilization

Creates a new IPv6 address representing localhost: ::1.

Examples

#![feature(ip_constructors)]
use std::net::Ipv6Addr;

let addr = Ipv6Addr::localhost();
assert_eq!(addr, Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1));

[src]

🔬 This is a nightly-only experimental API. (ip_constructors #44582)requires greater scrutiny before stabilization

Creates a new IPv6 address representing the unspecified address: ::

Examples

#![feature(ip_constructors)]
use std::net::Ipv6Addr;

let addr = Ipv6Addr::unspecified();
assert_eq!(addr, Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0));

[src]

Returns the eight 16-bit segments that make up this address.

Examples

use std::net::Ipv6Addr;

assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).segments(),
           [0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff]);

1.7.0
[src]

Returns true for the special 'unspecified' address (::).

This property is defined in IETF RFC 4291.

Examples

use std::net::Ipv6Addr;

assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_unspecified(), false);
assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0).is_unspecified(), true);

1.7.0
[src]

Returns true if this is a loopback address (::1).

This property is defined in IETF RFC 4291.

Examples

use std::net::Ipv6Addr;

assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_loopback(), false);
assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0x1).is_loopback(), true);

[src]

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

Returns true if the address appears to be globally routable.

The following return false:

  • the loopback address
  • link-local, site-local, and unique local unicast addresses
  • interface-, link-, realm-, admin- and site-local multicast addresses

Examples

#![feature(ip)]

use std::net::Ipv6Addr;
