@krlmlr You brought up the concept of roundtripping in a conversation
offline: I think that may be more of an issue for conversion from the other
side. In general, conversions to arrow (via nanoarrow or arrow) only happen
without error if the vector (and any associated metadata - like timezone or
unit) can be represented in Arrow losslessly. If you know the ptype that you
want back, `nanoarrow::convert_array_stream()` *should* be able to losslessly
roundtrip (e.g., `convert_array_stream(result, to = data.frame(x =
factor(levels = c("a", "b", ...)))`.
