class_docstr: Data in the buffer is guaranteed to be contiguous in memory.
  
  Note that there is no dtype attribute present, a buffer can be thought of
  as simply a block of memory. However, if the column that the buffer is
  attached to has a dtype that's supported by DLPack and ``__dlpack__`` is
  implemented, then that dtype information will be contained in the return
  value from ``__dlpack__``.
  
  This distinction is useful to support both data exchange via DLPack on a
  buffer and (b) dtypes like variable-length strings which do not have a
  fixed number of bytes per element.
