[][src]Struct no_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 no_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);

Implementations

impl Ipv6Addr[src]

pub const fn new(
    a: u16,
    b: u16,
    c: u16,
    d: u16,
    e: u16,
    f: u16,
    g: u16,
    h: u16
) -> Ipv6Addr
[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 no_std_net::Ipv6Addr;

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

pub const fn localhost() -> Ipv6Addr[src]

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

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

pub const fn unspecified() -> Ipv6Addr[src]
