Implementations

impl IpNetwork

pub fn new<I>( network_address: I, netmask: u8, ) -> Result<IpNetwork, IpNetworkError>

where I: Into<IpAddr>,

Constructs new IpNetwork based on IpAddr and netmask.

Examples

use std::net::{IpAddr, Ipv4Addr};
use std::str::FromStr;
use ip_network::{IpNetwork, Ipv4Network};

let network_address = IpAddr::V4(Ipv4Addr::new(192, 168, 1, 0));
let ip_network = IpNetwork::new(network_address, 24)?;
assert_eq!(ip_network.network_address(), IpAddr::V4(Ipv4Addr::new(192, 168, 1, 0)));
assert_eq!(ip_network.netmask(), 24);

pub fn new_truncate<I>( network_address: I, netmask: u8, ) -> Result<IpNetwork, IpNetworkError>

where I: Into<IpAddr>,

Constructs new IpNetwork based on IpAddr and netmask with truncating host bits from given network_address.

Returns error if netmask is bigger than 32 for IPv4 and 128 for IPv6.

Examples

use std::net::{IpAddr, Ipv4Addr};
use ip_network::IpNetwork;

let network_address = IpAddr::V4(Ipv4Addr::new(192, 168, 1, 128));
let ip_network = IpNetwork::new_truncate(network_address, 24)?;
assert_eq!(ip_network.network_address(), IpAddr::V4(Ipv4Addr::new(192, 168, 1, 0)));
assert_eq!(ip_network.netmask(), 24);

pub fn network_address(&self) -> IpAddr

Returns network IP address.

Examples

use std::net::{IpAddr, Ipv4Addr};
use ip_network::IpNetwork;

let ip_network = IpNetwork::new(Ipv4Addr::new(192, 168, 1, 0), 24)?;
assert_eq!(ip_network.network_address(), IpAddr::V4(Ipv4Addr::new(192, 168, 1, 0)));

pub fn netmask(&self) -> u8

Returns network mask as integer.

Examples

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

pub fn is_ipv4(&self) -> bool

Returns true if IpNetwork contains Ipv4Network struct.

pub fn is_ipv6(&self) -> bool

Returns true if IpNetwork contains Ipv6Network struct.

pub fn contains<I>(&self, ip: I) -> bool

where I: Into<IpAddr>,

Returns true if IpNetwork contains IpAddr. For different network type (for example IpNetwork is IPv6 and IpAddr is IPv4) always returns false.

Examples

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

let ip_network = IpNetwork::new(Ipv4Addr::new(192, 168, 1, 0), 24)?;
assert!(ip_network.contains(Ipv4Addr::new(192, 168, 1, 25)));

pub fn is_default_route(&self) -> bool

Returns true if the network is default route, that contains all IP addresses.

pub fn is_multicast(&self) -> bool

pub fn is_documentation(&self) -> bool

Returns true if this is a part of network reserved for documentation.

pub fn is_loopback(&self) -> bool

Returns true if this network is inside loopback address range.

pub fn is_global(&self) -> bool

Returns true if the network appears to be globally routable.

pub fn from_str_truncate(s: &str) -> Result<IpNetwork, IpNetworkParseError>

Converts string in format IPv4 (X.X.X.X/Y) or IPv6 (X:X::X/Y) CIDR notation to IpNetwork.

Examples

use std::net::Ipv4Addr;
use ip_network::{IpNetwork, Ipv4Network};

let ip_network = IpNetwork::from_str_truncate("192.168.1.1/24").unwrap();
assert_eq!(ip_network, IpNetwork::V4(Ipv4Network::new(Ipv4Addr::new(192, 168, 1, 0), 24).unwrap()));
