Generic pluggable key-value cache abstraction with interchangeable in-memory and Redis backends, a
hash-oriented API (HSetEX/HGet/etc.), plus a simple Set/Get/GetDel.
Key API
Cache[T Container] interface — Raw() T, HSetEX, HGet, HGetAll, HGetDelSingle, HLen, HExist, HDelSingle, Set, Get, MGet, GetDel, Exists, Del, Ping, Close.Container interface — *redis.Client | MemoryContainer.NewCache[T Container](container T) Cache[T] — type-switches to the matching backend; returns nil for an unsupported type.Memory struct + NewMemory(data, tickToClean) *Memory (starts a background TTL-sweeper goroutine); MemoryContainer struct + NewMemoryContainer() MemoryContainer.Redis struct + NewRedis(*redis.Client) *Redis (auto-detects DragonflyDB vs real Redis for the HSETEX variant).NewRedisClient(host, port, password, db, log) *redis.Client — dials and pings; Fatalf on failure.
Usage Notes
- Memory backend is thread-safe (
sync.RWMutex); TTL is enforced by a background goroutine that is weak-pointer based and auto-stops when the Memory is GC'd, or call Close() to stop it deterministically.
- Redis backend TTL relies on
HSETEX (Redis 7+) or DragonflyDB's variant, auto-detected via INFO server at construction.
- All errors are
yaerrors.Error; depends on yaerrors + yalogger. Used as a building block by yafsm, yaratelimit, yatgstorage, and yatgbot — prefer building on yacache rather than a raw redis.Client when you need caching, sessions, rate limiting, or state.
- Fx:
MemoryModule provides Cache[MemoryContainer]; RedisModule provides Cache[*redis.Client] (needs a yalogger.Logger in the graph) — pick one, not both (fx.go).
