How to construct a protocol header using proto buf (proto3) in python3 ?

[Manomugdha Biswas]

Hi,

I have following .proto file.

// [START declaration]

syntax = "proto3";

package tutorial;

// [END declaration]

// [START ICMP Echo Req messages]

message ICMP {

    int32 type = 1;

    int32 code = 2;

    int32 chksm = 3;

}

Here type is of 1 byte, code is of 1 byte, chksm is of 2 bytes. if given values are type=8, code=0, chksm=0x1234 then expected output after serialization is {0x08001234}. proto-buf gives '\x08\x01\x10\x02\x18\xb4$'.

Can i get the expected output using proto-buf?

Regards,

Mano
