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.
