Overview

This crate contains two data structures, [HashSetDelay] and [HashMapDelay]. These behave like the standard library HashSet and HashMaps with the added feature that entries inserted into the mappings expire after a fixed period of time.

Usage

Creating a map

```rust use delay_map::HashMapDelay; use futures::prelude::*;

// Set a default timeout for entries
let mut delay_map = HashMapDelay::new(std::time::Duration::from_secs(1));


tokio_test::block_on(async {

delay_map.insert(1, "entry_1");
delay_map.insert(2, "entry_2");

if let Some(Ok((key, value))) = delay_map.next().await {
    println!("Entry 1: {}, {}", key, value);  
}

if let Some(Ok((key, value))) = delay_map.next().await {
    println!("Entry 2: {}, {}", key,value);  
}
});

```
