template<typename Sig, bool Serializable = false>
class function

Class template hpx::function is a general-purpose polymorphic function wrapper. Instances of hpx::function can store, copy, and invoke any CopyConstructible Callable target &#8212; functions, lambda expressions, bind expressions, or other function objects, as well as pointers to member functions and pointers to data members. The stored callable object is called the target of hpx::function. If an hpx::function contains no target, it is called empty. Invoking the target of an empty hpx::function results in hpx::error::bad_function_call exception being thrown. hpx::function satisfies the requirements of CopyConstructible and CopyAssignable.
