Types

type Opaque

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

An Opaque represents payload that cannot be parsed by Lucius. Note opaque payload cannot be added or removed.

func (*Opaque) Field

func (op *Opaque) Field(id fwdpacket.FieldID) ([]byte, error)

Field returns a slice of bytes as identified by id.

func (*Opaque) Header

func (op *Opaque) Header() []byte

Header returns the opaque frame.

func (Opaque) ID

func (Opaque) ID(int) fwdpb.PacketHeaderId

ID returns the protocol header ID.

func (Opaque) Modify

func (Opaque) Modify(fwdpb.PacketHeaderId) error

Modify returns an error as the opaque header's type cannot be modified.

func (Opaque) Rebuild

func (Opaque) Rebuild() error

Rebuild does not perform any updates.

func (Opaque) Remove

func (Opaque) Remove(fwdpb.PacketHeaderId) error

Remove returns an error as the opaque header cannot be removed.

func (Opaque) Trailer

func (Opaque) Trailer() []byte

Trailer returns the no trailing bytes.

func (*Opaque) UpdateField

func (op *Opaque) UpdateField(id fwdpacket.FieldID, oper int, arg []byte) (bool, error)

UpdateField updates a slice of bytes identified by id.
