```D
module hunt.cache.adapter.Adapter;
import hunt.cache.Nullable;
interface Adapter
{
Nullable!V get(V) (string key);
Nullable!V[string] get(V) (string[] keys);
void set(V) (string key, V value, uint expired);
void set(V) (V[string] maps, uint expired);
bool setIfAbsent(V) (string key, V value);
bool hasKey(string key);
bool remove(string key);
void remove(string[] keys);
void clear();
}
