Detailed Description

Error that wraps any C++ exception.

This class can be used to catch any C++ exception (not just types inheriting from std::exception but also primitive types) and convert them to a Utils::Error, so that they compose nicely.

Usage example:

Robotics::Expected<int> myFunction() {
    try
    {
        int res = compute();
        switch (res)
        {
            case -1:
                throw 5;
            case -2:
                throw std::runtime_error("error computing my function");
            default:
                return res;
        }
    }
    catch (...)
    {
        return Robotics::ErrorException(std::current_exception());
    }
};
