Robust domain name parsing using the Public Suffix List

This library allows you to easily and accurately parse any given domain name.

Examples

use addr::{parse_domain_name, parse_dns_name};

// You can find out the root domain
// or extension of any given domain name
let domain = parse_domain_name("www.example.com")?;
assert_eq!(domain.root(), Some("example.com"));
assert_eq!(domain.suffix(), "com");

let domain = parse_domain_name("www.食狮.中国")?;
assert_eq!(domain.root(), Some("食狮.中国"));
assert_eq!(domain.suffix(), "中国");

let domain = parse_domain_name("www.xn--85x722f.xn--55qx5d.cn")?;
assert_eq!(domain.root(), Some("xn--85x722f.xn--55qx5d.cn"));
assert_eq!(domain.suffix(), "xn--55qx5d.cn");

let domain = parse_domain_name("a.b.example.uk.com")?;
assert_eq!(domain.root(), Some("example.uk.com"));
assert_eq!(domain.suffix(), "uk.com");

let name = parse_dns_name("_tcp.example.com.")?;
assert_eq!(name.suffix(), Some("com."));

// In any case if the domain's suffix is in the list
// then this is definately a registrable domain name
assert!(domain.has_known_suffix());
