    (#1603)
    Old code:

    let mut extra = HashMap::new();
    extra.insert(SomeExtra::Key1, "1".into());
    extra.insert(SomeExtra::Key2, "2".into());
    metric.record(extra);
    

    New code:

    let extra = SomeExtra {
        key1: Some("1".into()),
        key2: Some("2".into()),
    };
    metric.record(extra);
