r-cache

A simple caching library

r-cache is an in memory key value store. It is thread safe and values can have expiry times.

Example

use async_std::sync::Arc;
use async_std::task;
use r_cache::cache::Cache;
use std::time::Duration;

const KEY: i8 = 0;
const VALUE: &str = "VALUE";

#[async_std::main]
async fn main() {
    let cache = Arc::new(Cache::new(Some(Duration::from_secs(5 * 60))));
    task::spawn({
        let cache = Arc::clone(&cache);
        async move {
            loop {
                task::sleep(Duration::from_secs(10 * 60)).await;
                cache.remove_expired().await;
            }
        }
    });

    cache.set(KEY, VALUE, None).await;

    assert_eq!(VALUE, cache.get(&KEY).await.unwrap())
}
