Eggs.Variant is a C++11/14 generic, type-safe, discriminated union —see it on Github—.
The library requires a standard conformant implementation of C++11; a few additional features are only available under C++14. Some effort was done to support incomplete language or standard library implementations —see Config—. There are no external dependencies.
[Note: Older versions of Clang (3.0+) and GCC (4.6+) are no longer tested, but should still work; please report any issues if you are using them. Older versions of MSVC are not supported.]
