TF_Status* status);

  /// Returns the current write position in `*file`.
  ///
  /// Plugins should ensure that the implementation is idempotent, 2 identical
  /// calls result in the same answer.
  ///
  /// Plugins:
  ///   * Must set `status` to `TF_OK` and return current position if no error.
  ///   * Must set `status` to any other value and return -1 in case of error.

    *   Add functionality to SubSlice a tensor.
    *   Add searchsorted (ie lower/upper_bound) op.
    *   Add model explainability to Boosted Trees.
    *   Support negative positions for tf.substr.
    *   There was previously a bug in the bijector_impl where the
        _reduce_jacobian_det_over_event does not handle scalar ILDJ
        implementations properly.
