Async Throttle

Asynchronous Rate Limiting

This crate provides coarse and fine-grained ways to throttle the rate at which asynchronous tasks are executed.

Usage

Add this to your Cargo.toml:

toml [dependencies] async-throttle = "0.3.2"

You can use the fine-grained rate limiter like so:

```rust

[tokio::main]

async fn main() { let period = std::time::Duration::fromsecs(5); let ratelimiter = MultiRateLimiter::new(period);

// This completes instantly rate_limiter.throttle("foo", || computation()).await;

// This completes instantly rate_limiter.throttle("bar", || computation()).await;

// This takes 5 seconds to complete because the key "foo" is rate limited rate_limiter.throttle("foo", || computation()).await; } ```
