extendr::serializer::to_robj serializes integers as numerics

[JosiahParry]

rextendr::rust_function(r"-{
fn tst() -> Robj {
  let x = serde_json::Value::from(serde_json::Number::from(10i32));
  extendr_api::serializer::to_robj(&x).unwrap()
}

tst() |> class()
#> [1] "numeric"

I wanted to give this a shot but I don't know where this is being serialized. If anyone has an idea, I can give it a shot.

First, nice find. Second of all, I want to make you aware that the serializer doesn't really work with NA at the moment.

I also think that the path you're looking for starts with:

• serialize_value in deserializer.rs
• then to_robj, and notice here that the inner object is None.
