std::experimental::function is a modified version of std::function with support for type-erased allocators.
allocator_type [edit] Member functions [edit] Non-member functions [edit] Helper classes Members identical to std::function Member types Type Definition result_type R Member types removed in Library Fundamental TS v3 argument_type T if sizeof...(Args) == 1 and T is the first and only type in Args... first_argument_type T1 if sizeof...(Args) == 2 and T1 is the first of the two types in Args... second_argument_type T2 if sizeof...(Args) == 2 and T2 is the second of the two types in Args...
Member types argument_type, first_argument_type, and second_argument_type are removed, because the correponding member types of std::function are removed in C++20.
std::function instance
std::function<R(Args...)>) [edit] checks if a target is contained
std::function<R(Args...)>) [edit] invokes the target
std::function<R(Args...)>) [edit] Target access obtains the typeid of the stored target
std::function<R(Args...)>) [edit] obtains a pointer to the stored target
