Trait light_cache::policy::Prune

pub trait Prune<K, V, P> {
    // Required method
    fn prune<S: BuildHasher>(&mut self, cache: &LightCache<K, V, S, P>);
}

Prune should control how entries are expired (not nescessarily evicted) from the cache

Required Methods

fn prune<S: BuildHasher>(&mut self, cache: &LightCache<K, V, S, P>)

Prune is typically be called before any operation on the cache
