Function psl::init

pub fn init<U, D, L>(url: U, every: D, logger: L) -> Result<()> where
    U: IntoUrl,
    D: Into<Option<Duration>>,
    L: Into<Option<Logger>>, 

Initialise the list

Call from your main or run function. It fetches the list from url using a certain interval.

Example

extern crate psl;
extern crate publicsuffix;

use publicsuffix::LIST_URL;
use std::time::Duration;

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

    // Or update every 2 weeks
    psl::init(LIST_URL, Duration::from_secs(60 * 60 * 24 * 7 * 2), None).unwrap();
}

If it fails to fetch the list for the first time it will return an error. After it successfully fetches the list for the first time it will try to download an update at every interval retrying every 5 minutes if it fails.

If you are using this in a long running server, I highly recommend you set up a logger so you will know if updates start failing at some point in future.
