tokio-based leaky-bucket rate limiter

This project is a rate limiter based on the [leaky bucket] algorithm.

Usage

This library requires the user to add the following dependencies to use:

toml leaky-bucket = "0.5.0"

Examples

```rust use leaky_bucket::LeakyBuckets; use std::{error::Error, time::Duration};

[tokio::main]

async fn main() -> Result<(), Box> { let ratelimiter = LeakyBucket::builder() .max(100) .refillinterval(Duration::fromsecs(10)) .refillamount(100) .build()?;

println!("Waiting for permit...");
// should take about ten seconds to get a permit.
rate_limiter.acquire(100).await?;
println!("I made it!");

Ok(())

} ```
