Trait CacheStore 

pub trait CacheStore: Send + Sync {
    // Required methods
    fn get(&self, key: &CacheKey) -> Result<Option<Value>>;
    fn put(&self, key: &CacheKey, value: &Value) -> Result<()>;
    fn exists(&self, key: &CacheKey) -> Result<bool>;
    fn remove(&self, key: &CacheKey) -> Result<()>;
    fn metadata(&self, key: &CacheKey) -> Result<Option<EntryMeta>>;
}

The K/V cache store interface.

Implementations may be in-memory, on-disk (RocksDB/sled), or remote (S3). The tiered cache composes multiple stores.
