QUdpSocket : I'm receiving a struct, how do I use it?

Question

via a QUdpSocket, I know I'll receive datas which will contain only this struct:

typedef struct myStruct
    {
       int nb_trame;
       std::vector<bool> vBool;
    } myStruct;

but when I receive new datas, I receive a QByteArray right ? So how can I use the received-struct ?

It depends how this structure was serialized, before was sended to you. — tty6, May 25 '16 at 12:58
@tty6 just sending like that : `MyStruct data; viaUdp->write( (const char*) &data, sizeof (data));` — 0xPunt, May 25 '16 at 13:07

You can't entity-serialize a vector (your way of sending the struct is called entity-serialization). I mean, you can serialize it, but if you attempt to deserialize it this way you will not get a valid object.

You need to implement proper serialization.

So if I use a `bool myTab[20]` instead of my vector, It will be fine ? – 0xPunt May 25 '16 at 13:30
@BastienNicolau, entity-serialization is frown upon, and rightfuly so. It is OK in your pet project, but it usually has no place in production application. – SergeyA May 25 '16 at 13:38
