      mongodb rust driver version: 2.0.0.alpha.1

      std::mem::size_of::<mongodb::error::Error>() = 320
      std::mem::size_of::<mongodb::error::ErrorKind>() = 296

      It's not recommend to pass large object between function,

      I think Error or ErrorKind should allocate in heap memory and return a reference on function return value type

       

      `pubkind: ErrorKind` on mongodb::error::Error should change to `pubkind: Box<ErrorKind>`

       

      It's not effective to transfer 320 bytes mongodb::error::Error on stack memory
