Types

type Cache

type Cache interface {
	// Get gets the value of the given key.
	// If the key does not exist, the returned string will be empty ("").
	Get(ctx context.Context, key string) (string, error)
	// SetIfNotExists set key to hold string value if key does not exist (returning true).
	// If key exists, no operation is performed and false is returned as a result.
	// An expiration for the key has to be set. Zero expiration means the key is there forever.
	SetIfNotExists(
		ctx context.Context, key string, value string, expiration time.Duration,
	) (bool, error)
}
