QPromiseConversionException
Since: 0.7.0
This exception is thrown whenever a promise result conversion fails, for example:
QPromise<QVariant> input = {...};
auto output = input.convert<int>()
.fail([](const QPromiseconversionException& e) {
// conversion may fail because input could not be converted to number
});
