=head2 TF_StringStreamNext

=over 2

  Retrieves the next item from the given TF_StringStream and places a pointer
  to it in *result. If no more items are in the list, *result is set to NULL
  and false is returned.
  
  Ownership of the items retrieved with this function remains with the library.
  Item points are invalidated after a call to TF_StringStreamDone.

  Expose higher level Assignment operation for Pluggable vendors to implement
  in the plugin for Training. The API takes in the context with indices for
  the input and value tensors. It also accepts the copy callback provided by
  pluggable vendor to do the copying of the tensors. The caller takes ownership
  of the `source` and `dest` tensors and is responsible for freeing them with
  TF_DeleteTensor. This function will return an error when the following
  conditions are met:
    1. `validate_shape` is set to `true`
    2. The variable is initialized
    3. The shape of the value tensor doesn't match the shape of the variable
       tensor.
