Can't declare member of array type

[erunehtar]

If we do:

struct foo {
    float data[16];
};

namespace meta {
    template <> inline auto registerMembers<foo>() {
        return members(member("data", &foo::data));
    }
}

we get compile error function returns array because of the Member::getCopy function that returns by value.

Is there any template magic that can be done to disable this function (and all dependent calls) ?

Thank you, and nice job for this library!

Hello. I'll take a look at it soon, pretty sure it can be fixed with some SFINAE. :)

As a temporary workaround - std::array<float, 16> data works well. Looking for a proper fix at the moment.

[eliasdaler]

Can't fix this limitation easily - a lot of stuff needs a rewrite, so I can't promise a fix soon. :(

Ok thanks for looking into this. For the moment I can just comment out the function since I don't need to access members by copy.

Just an FYI, std::array didn't work for me, I had to swap to a vector, reserving the size. (Using MSVC C++20).

Hello I'm surprised that someone still uses this library, haha.

Why, don't you still use it?

[eliasdaler]

I don't. I think it's still useful, but I just didn't use it very much in my engine and decided that straightforward serialization/deserialization functions are easier to read/write. If your function have a lot of members and you need to serialize tons of types into multiple different formats, then it'll be quite useful still, indeed.
