# variant2
This repository contains a never-valueless, strong guarantee, C++11/14/17
implementation of [std::variant](http://en.cppreference.com/w/cpp/utility/variant).
See [the documentation](https://www.boost.org/libs/variant2)
for more information.
The code requires [Boost.Mp11](https://github.com/boostorg/mp11) and
Boost.Config.
The library is part of Boost, starting from release 1.71, but the header
`variant.hpp` will also work [standalone](https://godbolt.org/z/nVUNKX).
Supported compilers:
* g++ 4.8 or later with `-std=c++11` or above
* clang++ 3.5 or later with `-std=c++11` or above
* Visual Studio 2015, 2017, 2019
Tested on [Travis](https://travis-ci.org/boostorg/variant2/) and
[Appveyor](https://ci.appveyor.com/project/pdimov/variant2-fkab9).
