meta
Add "cxxstd" json field. The "cxxstd" json field is being added to each Boost library's meta json information for libraries whose minumum C++ standard compilation level is C++11 on up. The value of this field matches one of the values for 'cxxstd' in Boost.Build. The purpose of doing this is to provide information for the Boost website documentation for each library which will specify the minimum C++ standard compilation that an end-user must employ in order to use the particular library. This will aid end-users who want to know if they can successfully use a Boost library based on their C++ compiler's compilation level, without having to search the library's documentation to find this out.

variant2

This repository contains a never-valueless, strong guarantee, C++11/14/17 implementation of std::variant. See the documentation for more information.

The code requires Boost.Mp11 and Boost.Config.

The library is part of Boost, starting from release 1.71, but the header variant.hpp will also work standalone.

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 and Appveyor.
