Struct mio::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

fn new(
    a: u16,
    b: u16,
    c: u16,
    d: u16,
    e: u16,
    f: u16,
    g: u16,
    h: u16
) -> Ipv6Addr

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);

fn segments(&self) -> [u16; 8]

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]);

fn is_unspecified(&self) -> bool

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);

fn is_loopback(&self) -> bool

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);

fn is_global(&self) -> bool

🔬 This is a nightly-only experimental API. (ip)

extra functionality has not been scrutinized to the level that it should be stable

Returns true if the address appears to be globally routable.

The following return false:
