strict-variant | never empty and prevents undesirable implicit conversions

strict-variant is a C++ library. strict-variant has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

[boost licensed] do you use boost::variant or one of the many open-source c11 implementations of a "tagged union" or variant type in your c projects?. boost::variant is a great library. i created strict_variant in order to address a few things about boost::variant that i didn’t like. the tl;dr version is that unlike boost::variant or std::variant, strict_variant will never throw an exception or make a dynamic allocation in the effort of supporting types that have throwing moves. the default version will simply fail a static assert if this would happen. the strict_variant::easy_variant will make allocations in this situation, so you can opt-in to that if you want, and these two versions of variant "play nicely" together. this kind of thing is often a major concern in projects with realtime requirements,
