This create provide a simple way to use a counted cache system. When the count drop to zero, the cache delete the associated key, and the elements cannot be accessed anymore.
Here is an exemple:
use count_cache::CountCache;
fn main() {
let ccache = CountCache::new();
ccache.insert("test", 10.256, 2);
assert_eq!(ccache.get(&"test").expect("Err"), 10.256);
assert_eq!(ccache.get(&"test").expect("Err"), 10.256);
assert!(ccache.get(&"test").is_err());
assert!(ccache.get(&"test").is_err());
}
