False positive on code example

[ernado]

Example:

// Message represents a single STUN packet. It uses aggressive internal
// buffering to enable zero-allocation encoding and decoding,
// so there are some usage constraints:
//
// 	Message, its fields, results of m.Get or any attribute a.GetFrom
//	are valid only until Message.Raw is not modified.
//
// Usage:
// 	var m Message
// 	if err := m.Build(TransactionID, BindingRequest, Fingerprint); err != nil {
// 		panic(err)
// 	}
// You can call Build on zero value, and m.Raw will contain on-the-wire
// representation of Message. To decode message from byte slice, use Decode:
// 	var m Message
// 	if err := Decode(buf, &m); err != nil {
// 		panic(err)
// 	}
type Message struct {
	Type          MessageType
	Length        uint32 // len(Raw) not including header
	TransactionID [TransactionIDSize]byte
	Attributes    Attributes
	Raw           []byte
}

Yep, there was an issue, thanks for reporting.
Fixed in v0.3.4.
