Crate ipnet_trie

This crate provides storage and retrieval of IPv4 and IPv6 network prefixes.

Currently, it uses ipnet crate, that provides IP network data structure and treebitmap as backend, that provides fast lookup times, and a small memory footprint. Backend can be changed in future releases.

Examples

use std::net::{IpAddr, Ipv6Addr};
use ipnet::{IpNet, Ipv6Net};
use ipnet_trie::IpnetTrie;

let mut table = IpnetTrie::new();
let network = IpNet::from(Ipv6Net::new(Ipv6Addr::new(0x2001, 0xdb8, 0xdead, 0xbeef, 0, 0, 0, 0), 64).unwrap());
let ip_address = Ipv6Addr::new(0x2001, 0xdb8, 0xdead, 0xbeef, 0, 0, 0, 0x1);

assert_eq!(table.insert(network, "foo"), None);
// Get value for network from table
assert_eq!(table.longest_match(ip_address), Some((network, &"foo")));

Structs
