That’s a very interesting approach which I hadn’t considered. In my case I’m writing database drivers, so the cost of serde is non-trivial.
Like Derek mentioned, this is subjective, but I agree with Derek on this. Being primarily an Elixir/Erlang programmer, anything that makes the Rust/C side simpler is better in my book. In the case of a C-node in Rust, I would have to write a Rust wrapper over the ErlInterface API, which is definitely something I don’t want to get into.
Still, C-nodes seem like something worth investigating with potential applications later!
