Reading json array of size two in as a std::pair

[mtygesen]

I have the following json:

{
    "coordinates": [
        [57.0069969, 9.8778229],
        [57.0069945, 9.8777813], 
        [57.0069921, 9.8777397], 
        [57.0070376, 9.8777308]
    ]
}

which I want to read in as

struct Coordinate {
    double longitude;
    double latitude;
};

using Coordinates = std::vector<Coordinate>;

Is there any way to do this?

Managed to get it working with the following code

template <>
struct glz::meta<Coordinate> {
    using T = Coordinate;
    constexpr static auto value = glz::array(&T::longitude, &T::latitude);
};

template <>
struct glz::meta<Environment> {
    using T = Environment;
    constexpr static auto value =
        glz::object("coordinates", &T::coordinates);
};

Nice! That is the best approach.
