Constructs a primitive descriptor for LBR AUGRU forward propagation primitive.

The following arguments may point to a zero memory descriptor:

* ``src_iter_desc``,

* ``bias_desc``,

* ``dst_iter_desc``.

This would then indicate that the LBR AUGRU forward propagation primitive should not use them and should default to zero values instead.

.. note:: 

   All memory descriptors except ``src_iter_desc`` may be initialized with an :ref:`dnnl::memory::format_tag::any <doxid-structdnnl_1_1memory_1a8e71077ed6a5f7fb7b3e6e1a5a2ecf3fa100b8cad7cf2a56f6df78f171f97a1ec>` value of ``format_tag``.
