enumeration_name_vThe enumeration_name_v variable template provides a compile-time approach to retrieve the name of an enumeration type as a string literal. It is particularly useful for debugging, logging, or any scenario where the programmer needs to obtain the textual representation of an enumeration type rather than its underlying value.
template<concepts::strong_enum enum_type>
inline constexpr std::string_view enumeration_name_v;
enum_type: The enumeration type for which the name is desired. This template parameter should be an enumeration type satisfying a specific enum concept ensuring it’s an enum.std::string_view holding the name of the enumeration as defined in the code. This is a compile-time constant value.To utilize enumeration_name_v, ensure that your enumeration type is compatible with the concepts::strong_enum used in the template parameter.
#include <simple_enum/simple_enum.hpp>
#include <iostream>
enum class MyEnum { Value1, Value2 };
// Example usage of `enumeration_name_v`
std::cout << simple_enum::enumeration_name_v<MyEnum> << std::endl; // Output: "MyEnum"
This example demonstrates how to print the name of the enumeration MyEnum using enumeration_name_v. The output will be the name of the enumeration as specified in the code, i.e., “MyEnum”. The variable template enumeration_name_v simplifies accessing enumeration names without requiring runtime computations, thereby enhancing efficiency and code readability.
