Detailed Description

A functor class Printer for printing a value of any type.

This class can print values with all basic types, pointers, STL containers, tuple, optional, and variant values. Any class that is streamable can be printed. POD structs can be supported using third-party library Boost.PFR and enum can be supported using magic_enum.
