func Bool ¶

func Bool(reply interface{}, err error) (bool, error)

Bool is a helper that converts a command reply to a boolean. If err is not equal to nil, then Bool returns false, err. Otherwise Bool converts the reply to boolean as follows:

Reply type      Result
integer         value != 0, nil
bulk string     strconv.ParseBool(reply)
nil             false, ErrNil
other           false, error

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 Float64 ¶

func Float64(reply interface{}, err error) (float64, error)

Float64 is a helper that converts a command reply to 64 bit float. If err is not equal to nil, then Float64 returns 0, err. Otherwise, Float64 converts the reply to an int as follows:

Reply type    Result
bulk string   parsed reply, nil
nil           0, ErrNil
other         0, error

func Int ¶

func Int(reply interface{}, err error) (int, error)

Int is a helper that converts a command reply to an integer. If err is not equal to nil, then Int returns 0, err. Otherwise, Int converts the reply to an int as follows:

Reply type    Result
integer       int(reply), nil
bulk string   parsed reply, nil
nil           0, ErrNil
other         0, error

func Int64 ¶

func Int64(reply interface{}, err error) (int64, error)

Int64 is a helper that converts a command reply to 64 bit integer. If err is not equal to nil, then Int returns 0, err. Otherwise, Int64 converts the reply to an int64 as follows:

Reply type    Result
integer       reply, nil
bulk string   parsed reply, nil
nil           0, ErrNil
other         0, error

func MultiBulk ¶

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

MultiBulk is deprecated. Use Values.

func String ¶

func String(reply interface{}, err error) (string, error)

String is a helper that converts a command reply to a string. If err is not equal to nil, then String returns "", err. Otherwise String converts the reply to a string as follows:

Reply type      Result
bulk string     string(reply), nil
simple string   reply, nil
nil             "",  ErrNil
other           "",  error

func Strings ¶

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

Strings is a helper that converts an array command reply to a []string. If err is not equal to nil, then Strings returns nil, err. If one of the array items is not a bulk string or nil, then Strings returns an error.

func Uint64 ¶

func Uint64(reply interface{}, err error) (uint64, error)

Uint64 is a helper that converts a command reply to 64 bit integer. If err is not equal to nil, then Int returns 0, err. Otherwise, Int64 converts the reply to an int64 as follows:

Reply type    Result
integer       reply, nil
bulk string   parsed reply, nil
nil           0, ErrNil
other         0, error

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
