Detailed Documentation

Base class for primitive descriptors for RNN primitives.

Construction

rnn_primitive_desc_base()

Default constructor. Produces an empty object.

rnn_primitive_desc_base(
    dnnl_primitive_desc_t pd,
    dnnl::prop_kind aprop_kind,
    dnnl::algorithm cell_kind
    )

Constructs an RNN primitive descriptor base from a C API primitive descriptor while checking that it actually describes the expected primitive by comparing propagation and primitive kinds.

Parameters:

pd	C API primitive descriptor.
aprop_kind	Expected propagation kind.
cell_kind	Expected cell kind.
