Trait ipnet::IpSub

pub trait IpSub<RHS = Self> {
    type Output;
    fn saturating_sub(self, rhs: RHS) -> Self::Output;
}

Provides a saturating_sub() method for Ipv4Addr and Ipv6Addr.

Panics

When attempting to subtract an IpAddr::V4 from an IpAddr::V6 and vice versa.

Examples

use std::net::{Ipv4Addr, Ipv6Addr};
use std::str::FromStr;
use ipnet::IpSub;

let ip0 = Ipv4Addr::from_str("0.0.0.0").unwrap();
let ip1 = Ipv4Addr::from_str("1.1.1.1").unwrap();
let ip2 = Ipv4Addr::from_str("2.2.2.2").unwrap();

assert_eq!(ip0.saturating_sub(ip1), Ipv4Addr::from_str("0.0.0.0").unwrap());
assert_eq!(ip2.saturating_sub(ip1), Ipv4Addr::from_str("1.1.1.1").unwrap());
 
let ip60 = Ipv6Addr::from_str("::").unwrap();
let ip61 = Ipv6Addr::from_str("::1").unwrap();
let ip62 = Ipv6Addr::from_str("::2").unwrap();

assert_eq!(ip60.saturating_sub(ip61), Ipv6Addr::from_str("::").unwrap());
assert_eq!(ip62.saturating_sub(ip61), Ipv6Addr::from_str("::1").unwrap());
