Question

I am reading the type of an object from a file:

enum class type_index { ... };
type_index typeidx = read(file_handle, type_index{});

Answer 1

When you say I have the same generic code for different types; is it possible to wrap it all into a function with same prototype?

If so, you can map each type_index with a std::function in order to make the compiler to generate code for each type and to have an easy way to call every function in replacement to a switch.

Switch replacement:

function_map.at(read())();

Running example:

#include 
#include
