Is it possible to flatten fixed sized arrays to a single array?

Serialize

std::vector<Vec3> points = {{1,2,3} , {4,5,6} };

{
  "points" : [
        1,
        2,
        3,
        4,
        5,
        6
  ]
}

Deserialize

{
  "points" : [
        1,
        2,
        3,
        4,
        5,
        6
  ]
}

std::vector<Vec3>  points = { {1,2,3} {4,5,6} };

This feature is too specific to be added to this general-purpose JSON library. You may want to do the flattening/unflattening outside the library (see https://stackoverflow.com/questions/17294629/merging-flattening-sub-vectors-into-a-single-vector-c-converting-2d-to-1d for examples) and store std::vector<int> inside the JSON value. To avoid copies, you can use get_ref (see https://nlohmann.github.io/json/classnlohmann_1_1basic__json_afbd800010b67619463c0fce6e74f7878.html#afbd800010b67619463c0fce6e74f7878).

Thanks. I will give it a try.
