This library provides implementation of token bucket algorithm and some storage implementations.

```toml
[dependencies]
tocket = "0.2"
```

### Example
```rust
use tocket::{TokenBucket, InMemoryStorage};
use std::sync::Arc;
use std::time::Duration;

fn main() {
    let tb = TokenBucket::new(InMemoryStorage::new(100));
    let tb = Arc::new(tb);

    for i in 0..4 {
        std::thread::spawn({
            let tb = Arc::clone(&tb);
            move || {
                loop {
                    std::thread::sleep(Duration::from_secs(i));
                    
                    match tb.try_acquire_one() {
                        Ok(_) => println!("token acquired, limit not exceeded"),
                        Err(err) => eprintln!("token acquiring failed: {}", err),
                    }
                }
            }
        });
    }
    
    loop {}
}
```
