Trait ipnet::Contains [−] [src]

pub trait Contains<T> {
    fn contains(&self, _: T) -> bool;
}

Provides a method to test if a network contains another network or address.

Required Methods

Returns true if this network contains the given network or address.

Examples

use std::net::IpAddr;
use std::str::FromStr;
use ipnet::{IpNet, Contains};

Ipv4Net can contain other Ipv4Net and Ipv4Addr. let n1 = IpNet::from_str("10.1.1.0/24").unwrap(); let n2 = IpNet::from_str("10.1.1.0/26").unwrap(); let n3 = IpNet::from_str("10.1.2.0/26").unwrap(); let ip1 = IpAddr::from_str("10.1.1.1").unwrap(); let ip2 = IpAddr::from_str("10.1.2.1").unwrap(); assert!(n1.contains(&n2)); assert!(n1.contains(&ip1)); assert!(!n1.contains(&n3)); assert!(!n1.contains(&ip2)); Ipv6Net can contain other Ipv6Net and Ipv6Addr. let n6_1 = IpNet::from_str("fd00::/16").unwrap(); let n6_2 = IpNet::from_str("fd00::/17").unwrap(); let n6_3 = IpNet::from_str("fd01::/17").unwrap(); let ip6_1 = IpAddr::from_str("fd00::1").unwrap(); let ip6_2 = IpAddr::from_str("fd01::1").unwrap(); assert!(n6_1.contains(&n6_2)); assert!(n6_1.contains(&ip6_1)); assert!(!n6_1.contains(&n6_3)); assert!(!n6_1.contains(&ip6_2)); Ipv4Net and Ipv6Net types cannot contain each other. assert!(!n1.contains(&n6_1) || !n6_1.contains(&n1)); assert!(!n1.contains(&ip6_1) || !n6_1.contains(&ip1));
