Functions

func WriteArbitrary

func WriteArbitrary(w io.Writer, m interface{}) error

WriteArbitrary takes in any primitive golang value, or Message, and writes its encoded form to the given io.Writer, inferring types where appropriate.

func WriteArbitraryAsString

func WriteArbitraryAsString(w io.Writer, m interface{}) error

WriteArbitraryAsString is similar to WriteArbitrary except that it will encode all types except Array as a BulkStr, converting the argument into a string first as necessary. This is useful because commands to a redis server must be given as an array of bulk strings.

Note that if a Message type is found it will *not* be encoded to a BulkStr, but will simply be passed through as whatever type it already represents.

func WriteMessage

func WriteMessage(w io.Writer, m *Message) error

WriteMessage takes in the given Message and writes its encoded form to the given io.Writer

Types

type Message

type Message struct {
	Type
	// contains filtered or unexported fields
}

func NewMessage

func NewMessage(b []byte) (*Message, error)

NewMessagePParses the given raw message and returns a Message struct representing it

func ReadMessage

func ReadMessage(reader io.Reader) (*Message, error)

ReadMessage attempts to read a message object from the given io.Reader, parse it, and return a Message struct representing it

func (*Message) Array

func (m *Message) Array() ([]*Message, error)

Array returns the Message slice encompassed by this Messsage, assuming the Message is of type Array

func (*Message) Bytes

func (m *Message) Bytes() ([]byte, error)

Bytes returns a byte slice representing the value of the Message. Only valid for a Message of type SimpleStr, Err, and BulkStr. Others will return an error

func (*Message) Err

func (m *Message) Err() (error, error)

Err returns an error representing the value of the Message. Only valid for Err messages

func (*Message) Int

func (m *Message) Int() (int64, error)

Int returns an int64 representing the value of the Message. Only valid for Int messages

func (*Message) Str

func (m *Message) Str() (string, error)

Str is a Convenience method around Bytes which converts the output to a string

type Type

type Type int
const (
	SimpleStr Type = iota
	Err
	Int
	BulkStr
	Array
	Nil
)
