func ParsePacket

func ParsePacket(payload []byte, p ReceivablePacket) bool

Types

type Reader

type Reader struct {
	// contains filtered or unexported fields
}

Reader — маленький LE-ридер поверх байтового среза. Поддерживает readB/C/H/D/Q/F/S, hasRemaining и т.д.

func NewReader

func NewReader(b []byte) *Reader

func (*Reader) HasRemaining

func (r *Reader) HasRemaining() bool

func (*Reader) Offset

func (r *Reader) Offset() int

func (*Reader) ReadB

func (r *Reader) ReadB(dst []byte) error

func (*Reader) ReadBInto

func (r *Reader) ReadBInto(dst []byte, offset, n int) error

func (*Reader) ReadC

func (r *Reader) ReadC() (uint8, error)

func (*Reader) ReadD

func (r *Reader) ReadD() (int32, error)

func (*Reader) ReadF

func (r *Reader) ReadF() (float64, error)

func (*Reader) ReadH

func (r *Reader) ReadH() (uint16, error)

func (*Reader) ReadQ

func (r *Reader) ReadQ() (int64, error)

func (*Reader) ReadS

func (r *Reader) ReadS() (string, error)

func (*Reader) Remaining

	Read(r *Reader) bool
}

type SendablePacket

type SendablePacket interface {
	Write(w *Writer)
}

type Writer

type Writer struct {
	// contains filtered or unexported fields
}

Writer — аналог Java ByteBuffer с методами writeC/H/D/Q/F/B/S. По умолчанию работает в Little Endian (как L2J).
