//! Simple rate limiter for async tasks.
//!
//! Provides a structure to control rate of something. Something can be API calls to external
//! resource or anything you want to be limited to requests per interval.
//!
//! # Examples:
//! ```
//! // allows 1000 requests every 47 seconds to rick and morty api!
//! let limiter = RateLimiter::new(1000, Duration::from_secs(47));
//! for _ in 0..10000 {
//! let limiter = limiter.clone();
//! tokio::spawn(async move {
//! limiter.wait().await;
//! let body = reqwest::get("https://rickandmortyapi.com/api/episode/16")
//! .await
//! .unwrap()
//! .text()
//! .await
//! .unwrap();
//! });
//! }
//!```
