Trait 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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
