Serialization for QVector<QPair<size_t, double>>

[Fuel 0]

Why isnt it possible to serialize a QVector<QPair<size_t, double>> with QDatastream? I mean i use allowed Datatypes https://doc.qt.io/qt-5/datastreamformat.html .

Do i need an additional Implementation for that?

I tried with the below and it works perfectly. Make sure you have all the relevant includes at the top of your file

#include <QVector>
#include <QDataStream>
#include <QPair>
#include <QByteArray>
int main()
{
QByteArray temp;
QVector<QPair<size_t,double> > vect{{5u,2.5},{7u,3.3}};
QDataStream stream(&temp,QIODevice::WriteOnly);
stream << vect;
return 0;
}
