Detailed Description
This file contains the declaration of a two-element variant type.
This is necessary to work around an issue reported to LC in April 2021 regarding the use of the GCC 8 libstdc++ variant header with NVCC 11. As of July 2021 this has not been fixed. Additionally, the non-recursive implementation here should reduce compile times, though this effect may be limited for a variant with only two alternatives.
Definition in file variant.hpp.
