Module cache

LruCache implementation port from github.com/facebook/rocksdb. The class LruCache is thread-safe, because every operation on cache will be protected by a spin lock.

Structs

• CacheableEntry
• CleanCacheGuard
• LruCache
• LruCacheShard
• LruHandle
  An entry is a variable length heap-allocated structure. Entries are referenced by cache and/or by any external entity. The cache keeps all its entries in a hash table. Some elements are also stored on LRU list.
• LruHandleTable

Enums

• CachePriority
• LookupResponse
  lookup_with_request_dedup.await can directly return Result<CacheableEntry<K, T>, E>, but if we do not want to wait when cache hit does not happen, we can directly call lookup_with_request_dedup which will return a LookupResponse which contains Receiver<CacheableEntry<K, T>> or JoinHandle<Result<CacheableEntry<K, T>, E>> when cache hit does not happen.
