How to handle std::vector<char32_t>?

[siddhsql]

I have a struct that contains a

struct Result {
   ...
    std::vector<char32_t> data;
};

I originally mapped this as follows:

public static class Result extends Pointer {
        @StdVector
        public native IntPointer data(); 
    }

but it gives me this error when i try to compile:

error: no match for call to ‘(std::vector<char32_t>) ()’
  933 |         VectorAdapter< char32_t > radapter(ptr->data());

i then looked at this and changed to:

@StdVector @Cast("char32_t*")
        public native int[] data(); 

but I still get the same error. How can I fix this?

Try something like @Cast("char32_t*", "std::vector<char32_t>&") @StdVector IntPointer
