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.
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);
}
});
