Implementations

impl NetmaskExt

pub fn new(prefix: u8) -> NetmaskExt

Constructs a new NetmaskExt from a given prefix.

Example

use subnetwork::NetmaskExt;

fn main() {
    let netmask = NetmaskExt::new(24);
    // 255.255.255.0
    let netmask_ip = netmask.to_ipv4().unwrap();
}

pub fn from_addr(addr: IpAddr) -> NetmaskExt

Constructs a new NetmaskExt from a given IpAddr (like 255.255.255.0).

Example

use subnetwork::NetmaskExt;
use std::net::Ipv4Addr;
use std::net::IpAddr;

fn main() {
    let addr = IpAddr::V4(Ipv4Addr::new(255, 255, 255, 0));
    let netmask = NetmaskExt::from_addr(addr);
    // 255.255.255.0
    let prefix = netmask.get_prefix();
    assert_eq!(prefix, 24)
}

pub fn get_prefix(&self) -> u8

Return netmask address’s prefix length.

pub fn to_ipv4(&self) -> Result<Ipv4Addr, SubnetworkError>

Convert to Ipv4Addr address.

pub fn to_ipv6(&self) -> Result<Ipv6Addr, SubnetworkError>

Convert to Ipv6Addr address.
