I have a packet structure and I wish to serialize it into binary so I can send it through the wire.
There are many packet structures but I'll give the login packet as an example:
login struct {
seq uint8
id uint16
username [16]string
password [16]string
unknown1 [16]byte
}
I've read somewhere that you can't use binary.Write
for non-fixed size structures. But I believe my structure is fixed size (correct me if I'm wrong, I could be very wrong).
Now using this code:
var buf bytes.Buffer
x := login{
seq: 2,
id: 1,
username: [16]string{"username"},
password: [16]string{"password"},
}
err := binary.Write(&buf, binary.LittleEndian, x)
if err != nil {
log.Fatalln(err)
}
Gives me the error: binary.Write: invalid type main.login
Now, is there a way to fix this? Is there an alternative approach? Much like how you can use structs in C and send it through the network.
