Struct Ipv6Net

pub struct Ipv6Net { /* private fields */ }

An IPv6 network address.

See IpNet for a type encompassing both IPv4 and IPv6 network addresses.

Textual representation

Ipv6Net provides a FromStr implementation for parsing network addresses represented in CIDR notation. See IETF RFC 4632 for the CIDR notation.

Examples

use std::net::Ipv6Addr;
use ipnet::Ipv6Net;

let net: Ipv6Net = "fd00::/32".parse().unwrap();
assert_eq!(Ok(net.network()), "fd00::".parse());

Implementations

impl Ipv6Net

pub const fn new( ip: Ipv6Addr, prefix_len: u8, ) -> Result<Ipv6Net, PrefixLenError>

Creates a new IPv6 network address from an Ipv6Addr and prefix length.

Examples

use std::net::Ipv6Addr;
use ipnet::{Ipv6Net, PrefixLenError};

let net = Ipv6Net::new(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 24);
assert!(net.is_ok());

let bad_prefix_len = Ipv6Net::new(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 129);
assert_eq!(bad_prefix_len, Err(PrefixLenError));

pub const fn new_assert(ip: Ipv6Addr, prefix_len: u8) -> Ipv6Net

Creates a new IPv6 network address from an Ipv6Addr and prefix length. If called from a const context it will verify prefix length at compile time. Otherwise it will panic at runtime if prefix length is not less then or equal to 128.

Examples

use std::net::Ipv6Addr;
use ipnet::{Ipv6Net};

// This code is verified at compile time:
const NET: Ipv6Net = Ipv6Net::new_assert(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 24);
assert_eq!(NET.prefix_len(), 24);

// This code is verified at runtime:
let net = Ipv6Net::new_assert(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 24);
assert_eq!(net.prefix_len(), 24);

// This code does not compile:
// const BAD_PREFIX_LEN: Ipv6Net = Ipv6Net::new_assert(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 129);

// This code panics at runtime:
// let bad_prefix_len = Ipv6Addr::new_assert(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 129);

pub fn with_netmask( ip: Ipv6Addr, netmask: Ipv6Addr, ) -> Result<Ipv6Net, PrefixLenError>

Creates a new IPv6 network address from an Ipv6Addr and netmask.

Examples

use std::net::Ipv6Addr;
use ipnet::{Ipv6Net, PrefixLenError};

let net = Ipv6Net::with_netmask(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), Ipv6Addr::from(0xffff_ff00_0000_0000_0000_0000_0000_0000));
assert!(net.is_ok());

let bad_prefix_len = Ipv6Net::with_netmask(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), Ipv6Addr::from(0xffff_ff00_0000_0000_0001_0000_0000_0000));
assert_eq!(bad_prefix_len, Err(PrefixLenError));

pub fn trunc(&self) -> Ipv6Net

Examples

assert_eq!(
    "fd00::1:2:3:4/16".parse::<Ipv6Net>().unwrap().trunc(),
    "fd00::/16".parse().unwrap()
);

pub const fn addr(&self) -> Ipv6Addr

Returns the address.

pub const fn prefix_len(&self) -> u8

Returns the prefix length.

pub const fn max_prefix_len(&self) -> u8

Returns the maximum valid prefix length.

pub fn netmask(&self) -> Ipv6Addr

Returns the network mask.

Examples

let net: Ipv6Net = "fd00::/24".parse().unwrap();
assert_eq!(Ok(net.netmask()), "ffff:ff00::".parse());

pub fn hostmask(&self) -> Ipv6Addr

Returns the host mask.

Examples

let net: Ipv6Net = "fd00::/24".parse().unwrap();
assert_eq!(Ok(net.hostmask()), "::ff:ffff:ffff:ffff:ffff:ffff:ffff".parse());

pub fn network(&self) -> Ipv6Addr

Examples

let net: Ipv6Net = "fd00:1234:5678::/24".parse().unwrap();

pub fn broadcast(&self) -> Ipv6Addr

Returns the last address.

Technically there is no such thing as a broadcast address for IPv6. The name is used for consistency with colloquial usage.

Examples

let net: Ipv6Net = "fd00:1234:5678::/24".parse().unwrap();
assert_eq!(Ok(net.broadcast()), "fd00:12ff:ffff:ffff:ffff:ffff:ffff:ffff".parse());

Returns true if this network and the given network are children of the same supernet.

Examples

let n1: Ipv6Net = "fd00::/18".parse().unwrap();

let n3: Ipv6Net = "fd00:8000::/18".parse().unwrap();

assert!(n1.is_sibling(&n2));
assert!(!n2.is_sibling(&n3));

pub fn hosts(&self) -> Ipv6AddrRange

Return an Iterator over the host addresses in this network.

Examples

let net: Ipv6Net = "fd00::/126".parse().unwrap();
assert_eq!(net.hosts().collect::<Vec<Ipv6Addr>>(), vec![
    "fd00::".parse::<Ipv6Addr>().unwrap(),
    "fd00::1".parse().unwrap(),
    "fd00::2".parse().unwrap(),
    "fd00::3".parse().unwrap(),
]);

pub fn subnets(&self, new_prefix_len: u8) -> Result<Ipv6Subnets, PrefixLenError>

Examples

    "fd00::1/128".parse().unwrap(),
    "fd00::2/128".parse().unwrap(),
    "fd00::3/128".parse().unwrap(),
]);

let net: Ipv6Net = "fd00::/16".parse().unwrap();
assert_eq!(net.subnets(15), Err(PrefixLenError));

let net: Ipv6Net = "fd00::/16".parse().unwrap();
assert_eq!(net.subnets(129), Err(PrefixLenError));

pub fn contains<T>(&self, other: T) -> bool

where Self: Contains<T>,

Test if a network address contains either another network address or an IP address.

Examples

let net: Ipv6Net = "fd00::/16".parse().unwrap();
