Hi again, this is table features again, but albeit with less work done on the main branch like the smart guy I am.

Should we capture this value using an untagged variant instead?

Something like this

#[derive(serde::Deserialize, serde::Serialize, Debug, Clone)]
pub enum Example {
    Foo,
    Bar,
    #[serde(untagged)]
    Unknown(String),
}

#[derive(serde::Deserialize, serde::Serialize, Debug, Clone)]
struct Features {
    reader: Vec<Example>
}

fn main() {
    let features = Features { 
        reader: vec![Example::Foo, Example::Bar, Example::Unknown("Hello".to_string())],
    };
    println!("{}", serde_json::to_string(&features).unwrap());
    let features: Features = serde_json::from_str(r#"{"reader":["Foo","Bar","Hello"]}"#).unwrap();
    println!("{:#?}", features);
}
