Struct ipnetwork::Ipv4Network

pub struct Ipv4Network { /* fields omitted */ }

Represents a network range where the IP addresses are of v4

Methods

impl Ipv4Network

pub fn new(addr: Ipv4Addr, prefix: u8) -> Result<Ipv4Network, IpNetworkError>

Constructs a new Ipv4Network from any Ipv4Addr and a prefix denoting the network size. If the prefix is larger than 32 this will return an IpNetworkError::InvalidPrefix.

pub fn iter(&self) -> Ipv4NetworkIterator

Returns an iterator over Ipv4Network. Each call to next will return the next Ipv4Addr in the given network. None will be returned when there are no more addresses.

pub fn ip(&self) -> Ipv4Addr

pub fn prefix(&self) -> u8

pub fn mask(&self) -> Ipv4Addr

Returns the mask for this Ipv4Network. That means the prefix most significant bits will be 1 and the rest 0

Examples

use std::net::Ipv4Addr;
use ipnetwork::Ipv4Network;

let net: Ipv4Network = "127.0.0.0/16".parse().unwrap();
assert_eq!(net.mask(), Ipv4Addr::new(255, 255, 0, 0));

pub fn network(&self) -> Ipv4Addr

Returns the address of the network denoted by this Ipv4Network. This means the lowest possible IPv4 address inside of the network.

Examples

use std::net::Ipv4Addr;
use ipnetwork::Ipv4Network;

let net: Ipv4Network = "10.1.9.32/16".parse().unwrap();
assert_eq!(net.network(), Ipv4Addr::new(10, 1, 0, 0));

pub fn broadcast(&self) -> Ipv4Addr

Returns the broadcasting address of this Ipv4Network. This means the highest possible IPv4 address inside of the network.

Examples

use std::net::Ipv4Addr;
use ipnetwork::Ipv4Network;

let net: Ipv4Network = "10.9.0.32/16".parse().unwrap();
assert_eq!(net.broadcast(), Ipv4Addr::new(10, 9, 255, 255));

pub fn contains(&self, ip: Ipv4Addr) -> bool

Checks if a given Ipv4Addr is in this Ipv4Network

Examples

use std::net::Ipv4Addr;
use ipnetwork::Ipv4Network;

let net: Ipv4Network = "127.0.0.0/24".parse().unwrap();
assert!(net.contains(Ipv4Addr::new(127, 0, 0, 70)));
assert!(!net.contains(Ipv4Addr::new(127, 0, 1, 70)));

pub fn size(&self) -> u64

Returns number of possible host addresses in this Ipv4Network.

Examples

use std::net::Ipv4Addr;
use ipnetwork::Ipv4Network;

let net: Ipv4Network = "10.1.0.0/16".parse().unwrap();
assert_eq!(net.size(), 65536);

let tinynet: Ipv4Network = "0.0.0.0/32".parse().unwrap();
assert_eq!(tinynet.size(), 1);

pub fn nth(&self, n: u32) -> Option<Ipv4Addr>

Returns the n:th address within this network. The adresses are indexed from 0 and n must be smaller than the size of the network.

Examples

use std::net::Ipv4Addr;
use ipnetwork::Ipv4Network;

let net: Ipv4Network = "192.168.0.0/24".parse().unwrap();
assert_eq!(net.nth(0).unwrap(), Ipv4Addr::new(192, 168, 0, 0));
assert_eq!(net.nth(15).unwrap(), Ipv4Addr::new(192, 168, 0, 15));
assert!(net.nth(256).is_none());

let net2: Ipv4Network = "10.0.0.0/16".parse().unwrap();
assert_eq!(net2.nth(256).unwrap(), Ipv4Addr::new(10, 0, 1, 0));
