Serializing a vector fails

[Stock84-dev]

Serializing struct with vector fails with: thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: UnsupportedOperation { operation: "serialize_seq" }. I see that unit tests contain vectors so it should be supported. But they are marked with #[ignore] Demo code:

#[derive(Serialize, Deserialize)]
struct ABC {
    abc: f32,
}

#[derive(Serialize, Deserialize)]
struct ABC2 {
    #[serde(rename = "$value", default)]
    items: Vec<ABC>,
}

fn main() {
    let abc = ABC2 {
        items: vec![ABC { abc: 1. }],
    };
    debug!("{:#?}", serde_xml_rs::to_string(&abc).unwrap());
}

I think this should be fixed with #129.

I get to the very end of a project and discover this doesn't work..

Also get the same for this structure

#[derive(Debug, Serialize, Deserialize)]
pub struct Data {
    pub name: String,
    pub list: Vec<bool>,
}

Sorry for being a bit off-topic, but I ran into the same issue as well and found a workaround: you could try to use https://github.com/tafia/quick-xml as a drop-in replacement until this issue is resolved.

@woelper That ended up being my solution too.

how can i serialize a struct with vec?!

[punkstarman]

Sorry that the serializer isn't complete yet. As soon as I have some time, I've got some stuff in the works for revamping and completing the serializer.

@Curricane, if you are in a hurry, you can have a look at the project where I did some experimentation: https://github.com/punkstarman/serde-xml

@punkstarman Does the serializer completed in #173 and mentioned as a solution to #76 also fix this issue?

If so, is there any chance of a release in the near future?

[punkstarman]

@zmrow I will check and try to release in the next week.

[punkstarman]

I just released a new version.

This appears to be fixed in the new version.
