    Hello All,

    ๐Ÿš€ I'm happy to announce the second release of metajson, the json de/serializer I've been playing with for few weeks.

    It includes:

    • ๐Ÿ‘Œ Support of standard types: std::variant, std::optional and std::tuple
    • โšก๏ธ Generation of error messages, optimized for low overhead.
    • A benchmark on a large json file canada.json, taken from
    • ๐Ÿ›  Few bug fixes

    ๐Ÿ‘€ From the benchmarks, the library seems to deserialize small objects faster than other libraries, and large objects ~10% slower than rapidjson. See some numbers below.

    ๐Ÿš€ The plan for the future is to deliver monthly releases as long as you or I find potential improvements. Feel free to push features requests or issues.

    ๐Ÿš€ This is the first release of the library. All the features are completed and the code have been optimized to beat the rapidjson library, #1 on the miloyip's benchmark

    I also made a script to generate a single header version, easier to install:
