Interface Layer

base.go:19–27

Layer represents a single decoded packet layer (using either the OSI or TCP/IP definition of a layer). When decoding, a packet's data is broken up into a number of layers. The caller may call LayerType() to figure out which type of layer they've received from the packet. Optionally, they may then

// they may then use a type assertion to get the actual layer type for deep
// inspection of the data.
type Layer interface {
	// LayerType is the gopacket type for this layer.
	LayerType() LayerType
	// LayerContents returns the set of bytes that make up this layer.
	LayerContents() []byte
	// LayerPayload returns the set of bytes contained within this layer, not
	// including the layer itself.
	LayerPayload() []byte
}

// Payload is a Layer containing the payload of a packet.  The definition of
// what constitutes the payload of a packet depends on previous layers; for
