func ByteSlices ¶

func ByteSlices(reply interface{}, err error) ([][]byte, error)

ByteSlices is a helper that converts an array command reply to a [][]byte. If err is not equal to nil, then ByteSlices returns nil, err. Nil array items are stay nil. ByteSlices returns an error if an array item is not a bulk string or nil.

func Bytes ¶

func Bytes(reply interface{}, err error) ([]byte, error)

Bytes is a helper that converts a command reply to a slice of bytes. If err is not equal to nil, then Bytes returns nil, err. Otherwise Bytes converts the reply to a slice of bytes as follows:

Reply type      Result
bulk string     reply, nil
simple string   []byte(reply), nil
nil             nil, ErrNil
other           nil, error

func Int64Map ¶

func Int64Map(result interface{}, err error) (map[string]int64, error)

Int64Map is a helper that converts an array of strings (alternating key, value) into a map[string]int64. The HGETALL commands return replies in this format. Requires an even number of values in result.

func IntMap ¶

func IntMap(result interface{}, err error) (map[string]int, error)

IntMap is a helper that converts an array of strings (alternating key, value) into a map[string]int. The HGETALL commands return replies in this format. Requires an even number of values in result.

func Positions ¶

func Positions(result interface{}, err error) ([]*[2]float64, error)

Positions is a helper that converts an array of positions (lat, long) into a [][2]float64. The GEOPOS command returns replies in this format.

func StringMap ¶

func StringMap(result interface{}, err error) (map[string]string, error)

StringMap is a helper that converts an array of strings (alternating key, value) into a map[string]string. The HGETALL and CONFIG GET commands return replies in this format. Requires an even number of values in result.

func Values ¶

func Values(reply interface{}, err error) ([]interface{}, error)

Values is a helper that converts an array command reply to a []interface{}. If err is not equal to nil, then Values returns nil, err. Otherwise, Values converts the reply as follows:

Reply type      Result
array           reply, nil
nil             nil, ErrNil
other           nil, error
