Detailed Description

template<typename RT = void>
class Threads::Task< RT >::TaskData

A data structure that holds a std::future into which the task deposits its return value. Since one can only call std::future::get() once, we do so in the get() member function and then move the returned object into the returned_object member variable from where we can read it multiple times and from where it can also be moved away if it is not copyable.
