Types

type Data

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

func NewData

func NewData(sz int) *Data

func (*Data) Buf

func (d *Data) Buf() []byte

Buf returns this Data's buffer. This is the buffer that should be used everywhere except for the tun.Device ReadPacket and WritePacket methods.

func (*Data) Copy

func (d *Data) Copy(n int) *Data

Copy copies n bytes from the given Data buffer into a new Data and returns it.

func (*Data) Raw

func (d *Data) Raw() []byte

Raw returns this Data's raw buffer. This is the buffer that should be used by the tun.Device ReadPacket and WritePacket methods. It uses the same underlying byte array as Buf but might be offset before Buf to allow for leading bytes that are provided before the IP header.

func (*Data) Resize

func (d *Data) Resize(size int)
