Module rnn 

RNN / LSTM / GRU forward + backward training requests.

Routes through cuDNN’s RNN v8 API (cudnnRNNForward / cudnnRNNBackwardData_v8 / cudnnRNNBackwardWeights_v8).

Structs

RnnBwdRequest

RNN backward (data + weights) request.

RnnFwdRequest

RNN forward request.

RnnParams

RNN parameters.

Enums

RnnDirection

Direction.

RnnMode

RNN cell mode.

Functions

build_rnn_fwd_spec

Build a spec-side OperationGraphSpec for plan-cache keying. The actual RNN API does not use the v9 backend graph descriptor builder — but we keep a stable signature surface so the cache key machinery is shared.
