Reopening: Feature request: Serde flatten for extra properties (derive Clone for Variant) #108

[ThalusA]

Hi, I'm reopening this issue based on the fact that I have now another error. #108
Now I don't have any error doing #[serde(flatten)] pub extra: HashMap<String, Variant> while compiling but I have an error at runtime: Expected a named struct. Hint: You cannot use a HashMap<...> in this context because it requires the struct to have a name. I'm at the time trying to find a solution for that but it seems what I want to do doesn't seems possible yet

I just want to be able to do exactly that : https://serde.rs/attr-flatten.html#capture-additional-fields

See #110 for a more complete solution, but you can do this even without it using raw_query:

#[derive(Deserialize, Debug)]
struct Win32_OperatingSystem {
    Caption: String,
    Name: String,

    #[serde(flatten)]
    extra: HashMap<String, Variant>,
}

let system: Vec<Win32_OperatingSystem> = wmi_con
    .raw_query("SELECT * FROM Win32_OperatingSystem")
    .unwrap();
