Object encoding details

Objects are encoded in three different forms, depending on whether the object was nil, or was already encoded to the stream. If the object is non-nil and is encoded for the first time for a given Encoder then the object is encoded as:

key  uint32   // A unique identifier for the object instance
type [20]byte // A unique identifier for the type of the object
...data...    // The object's data (length dependent on the object type)

All subsequent encodings of the object are encoded as the 16 bit key identifier without any additional data:

key uint32 // An identifier of a previously encoded object instance

If the object is nil, then the object is encoded as a uint32 of 0.

Usage

func Decoder

func Decoder(reader binary.Reader) *decoder

Decoder creates a binary.Decoder that reads from the provided binary.Reader.

func Encoder

func Encoder(writer binary.Writer) binary.Encoder

Encoder creates a binary.Encoder that writes to the supplied binary.Writer.
