* To check if nameof_type_rtti is supported by your compiler use macro `NAMEOF_TYPE_RTTI_SUPPORTED` or constexpr constant `nameof::is_nameof_type_rtti_supported`.</br>
If nameof_type_rtti is used on an unsupported compiler, a compilation error occurs. To suppress the error define the macro `NAMEOF_TYPE_NO_CHECK_SUPPORT`.
* To check is nameof_member supported compiler use macro `NAMEOF_MEMBER_SUPPORTED` or constexpr constant `nameof::is_nameof_member_supported`.</br>

If nameof_pointer used on unsupported compiler, occurs the compilation error. To suppress error define macro `NAMEOF_TYPE_NO_CHECK_SUPPORT`.
## Nameof Enum
* This library uses a compiler-specific hack (based on `__PRETTY_FUNCTION__` / `__FUNCSIG__`), which works on Clang >= 5, MSVC >= 15.3 and GCC >= 9.
