This library uses Mozilla's [Public Suffix List](https://publicsuffix.org) to reliably determine the suffix of a domain name. This crate provides a dynamic list that can be updated at runtime. If you need a faster, though static list, please use the [psl](https://crates.io/crates/psl) crate instead.

*NB*: v1 of this crate contained logic to validate domain names and email addresses. Since v2, this functionality was moved to the [addr](https://crates.io/crates/addr) crate. This crate also no longer downloads the list for you.

## Setting Up

Add this crate to your `Cargo.toml`:

```toml

[dependencies]

publicsuffix = "2"

```

## Examples

```rust

use publicsuffix::{Psl, List};

// the official list can be found at

// https://publicsuffix.org/list/public_suffix_list.dat

let list: List = "<-- your public suffix list here -->".parse()?;

let suffix = list.suffix(b"www.example.com")?;

assert_eq!(suffix, "com");

assert_eq!(suffix.typ(), Some(Type::Icann));

let domain = list.domain(b"www.example.com")?;

assert_eq!(domain, "example.com");

assert_eq!(domain.suffix(), "com");

let domain = list.domain("www.食狮.中国".as_bytes())?;

assert_eq!(domain, "食狮.中国");

assert_eq!(domain.suffix(), "中国");

let domain = list.domain(b"www.xn--85x722f.xn--55qx5d.cn")?;

assert_eq!(domain, "xn--85x722f.xn--55qx5d.cn");

assert_eq!(domain.suffix(), "xn--55qx5d.cn");

let domain = list.domain(b"a.b.example.uk.com")?;

assert_eq!(domain, "example.uk.com");

assert_eq!(domain.suffix(), "uk.com");

let domain = list.domain(b"_tcp.example.com.")?;

assert_eq!(domain, "example.com.");

assert_eq!(domain.suffix(), "com.");

```
