var ( // ErrLockNotAcquired 表示锁已被其他持有者占用。 ErrLockNotAcquired = errors.New("redis: lock not acquired") // ErrLockNotHeld 表示当前实例不持有该锁（已过期或 token 不匹配）。 ErrLockNotHeld = errors.New("redis: lock not held") )
Functions ¶
func GetOrSet ¶
func GetOrSet[T any]( ctx context.Context, c *Client, key string, ttl time.Duration, loader func(ctx context.Context) (T, error), marshal func(T) (string, error), unmarshal func(string) (T, error), ) (T, error)
GetOrSet 实现 Cache-aside 模式。 查缓存 → 未命中调用 loader → 写回缓存。 Redis 读取失败时降级为直接调用 loader（缓存故障不阻塞业务）。
Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
