delay_map

Documentation at docs.rs

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

    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);  
    }
    });
