This crate was born out of the desire for a simple configurable stream that would yield ever changing, yet predictable values.

The num_stream method can be used to acquire an instance of a NumStream struct which implements a Futures 0.3 Stream.

#[tokio::main]
async fn main() {
    let mut nums = num_stream(0, 3, Duration::from_millis(500));
    loop {
        println!("Got: {:?}", nums.next().await);
    }
}
