Examples

Limit calls to an API to 5 per second, or lockout for one minute

use throttle_lock::Throttle;

let mut counter = Throttle::new(1000, 5, 1000*60);
if counter.is_throttled() {
    println!("Try again later")
}

Limit signin attempts on an email address to 5 per minute, or lockout for 5 minutes.

use throttle_lock::ThrottleHash;

let mut counter = ThrottleHash::new(60*1000, 5, 3*60*1000);
let email:String = "john@example.com".to_string();
if counter.is_throttled(&email) {
    println!("Try again later")
}
