Crate clock_cache

An implemenation of a CLOCK cache as first described in [A Paging Experiment with the Multics System] (http://multicians.org/paging-experiment.pdf).

Example

extern crate clock_cache;

use clock_cache::ClockCache;

fn main() {
        let mut cache = ClockCache::new(2);
        cache.put("apple", "red");
        cache.put("banana", "yellow");

        assert_eq!(*cache.get(&"apple").unwrap(), "red");
        assert_eq!(*cache.get(&"banana").unwrap(), "yellow");
        assert!(cache.get(&"pear").is_none());

        cache.put("pear", "green");

        assert_eq!(*cache.get(&"pear").unwrap(), "green");
        assert_eq!(*cache.get(&"banana").unwrap(), "yellow");
        assert!(cache.get(&"apple").is_none());
}
