如何使用serde_xml_rs将XML反序列化为基于标记名的不同结构？

[dependencies]
serde = "1.0"
serde_xml_rs = "0.5"

use serde::Deserialize;

#[derive(Debug, Deserialize)]
struct Person {
    #[serde(rename = "name")]
    name: String,
    #[serde(rename = "age")]
    age: u32,
}

use serde_xml_rs::from_str;

let xml = r#"
    <person>
        <name>John Doe</name>
        <age>30</age>
    </person>
"#;

let person: Person = from_str(xml).unwrap();
println!("{:?}", person);

use serde::Deserialize;

#[derive(Debug, Deserialize)]
struct People {
    #[serde(rename = "person")]
    people: Vec<Person>,
}

use serde_xml_rs::from_str;

let xml = r#"
    <people>
        <person>
            <name>John Doe</name>
            <age>30</age>
        </person>
        <person>
            <name>Jane Smith</name>
            <age>25</age>
        </person>
    </people>
"#;

let people: People = from_str(xml).unwrap();
println!("{:?}", people);
