Functions

func Marshal 

func Marshal(g Message) ([]byte, error)

Marshal returns the byte sequence generated from a Message instance. Better to use MarshalXxx instead if you know the name of message to be serialized.

func NewHeaderFlags 

func NewHeaderFlags(v, p, e, s, n int) uint8

NewHeaderFlags returns a Header Flag built by its components given as arguments.

func Prettify added in v0.7.19 

func Prettify(m Message) string

Prettify returns a Message in prettified representation in string.

Note that this relies much on reflect package, and thus the frequent use of this function may have a serious impact on the performance of your software.

func Serialize deprecated 

func Serialize(m Message) ([]byte, error)

Serialize serializes Message into bytes.

Deprecated: use Marshal instead.
