}

#[derive(Debug, Deserialize)]
struct Item {
    name: String,
    source: String,
}

fn main() {
    let s = r#"{
        "name": "test",
        "items": {
            "item": [
            {

            ]
        }
        }"#;
    let project: Project = serde_json::from_str(s).expect("deserialize failed");
    assert_eq!(project.name, "test");
    assert_eq!(project.items.len(), 1);
    let item = &project.items[0];
    assert_eq!(item.name, "name");
    assert_eq!(item.source, "name.rs");
