Variables

var LayerTypeHTTP2 = gopacket.RegisterLayerType(12345, gopacket.LayerTypeMetadata{Name: "HTTP2", Decoder: gopacket.DecodeFunc(decodeHTTP2)})

Create a layer type, should be unique and high, so it doesn't conflict, giving it a name and a decoder to use.

var State = &HeadersState{state: map[ipTcpConn]map[string]string{}}
