Types

type Cache

type Cache[K comparable, V any] interface {
	// Get 获取缓存值
	Get(ctx context.Context, key K) (V, bool)
	// Set 设置缓存值
	Set(ctx context.Context, key K, value V, ttl time.Duration) error
	// Delete 删除缓存
	Delete(ctx context.Context, key K) error
	// Clear 清空缓存
	Clear(ctx context.Context) error
	// Name 获取缓存名称
	Name() string
