) -> GhosttyResult

Set an option on the current row in a render-state row iterator.

The value pointer must point to a value of the type corresponding to the requested option kind (see GhosttyRenderStateRowOption). Call ghostty_render_state_row_iterator_next() at least once before calling this function.
