A cache manager for the publicsuffix crate

The publicsuffix crate is a low level crate that allows you to optionally use Mozilla's Public Suffix List to parse domain names and email addresses. It provides methods for fetching the list but it doesn't try to handle caching for you. If you use the list in long running applications, you need a way to keep the list updated. This is where this crate comes in. It downloads the list at a specific interval (every week by default).

This initial version only keeps a cache in memory. If you restart your application, your current cache will be lost so the list will be downloaded again.

Quick Start

Add this crate to your dependencies:-

```toml [dependencies] psl = "0.0.1" publicsuffix = "1.3"

The following crates are optional but recommended. Without logging,

you won't know if updates start failing in future.

slog = "1.2" slog-term = "1.3" ```

Call init from your main.rs:-

```rust extern crate psl; extern crate publicsuffix; extern crate slog; extern crate slog_term;

use publicsuffix::LIST_URL; use slog::{Logger, DrainExt};

fn main() { // Initialise the list psl::init(LIST_URL, None).unwrap();

// Set up logging let log = Logger::root(slogterm::streamer().build().fuse(), o!("version" => env!("CARGOPKGVERSION"))); psl::setlogger(&log); }

fn anywhere() -> Result<()> { // To get access to an instance of the cached list call psl::get(). For example... let domain = psl::get().parse_domain("example.com")?; } ```
