I created a demo with dynamic link crossdb: crossdb-rs-dylib, which runs perfectly on Linux. You can take a look. If you need static link, you can refer to this repo (there are still some warnings.

If you need more help, please give me some detailed information.

xdb_column_... require col_meta, which comes from res, but your res is a pointer. You need to convert it to a struct first and then retrieve col_meta from it.

https://crossdb.org/client/api-c/#xdb_column_int

+ let res = *res;
 for i in 0..3 {
    match i {
        0 | 2 => {
-           let value = xdb_column_int(res as u64, row, i);
+           let value = xdb_column_int(res.col_meta, row, i);
            println!("Column {}: {}", i, value);
        }
        1 => {
-            let ptr = xdb_column_str(res as u64, row, i);
+            let ptr = xdb_column_str(res.col_meta, row, i);
          ...
        _ => unreachable!(),
    }
}
