docker + distroless 镜像 + python 应该不能更精简了

同新手,是我的话可能会用 quick-xml 和 serde
```rust
// serde = { version = "1.0", features = [ "derive" ] }
// quick-xml = { version = "0.22", features = [ "serialize" ] }
use std::fs;
use serde::{Serialize,Deserialize};
use quick_xml::de::from_str;
use quick_xml::se::to_string;


#[derive(Serialize,Deserialize)]
#[serde(rename = "this_tag")]
struct Thistag {
k1: Option<String>,
k2: Option<String>,
child: String,
atag: String
}


fn main() {
//let s = fs::read_to_string("test.xml").unwrap();
let s = r#"<this_tag k1="v1" k2="v2">
<child>
text
</child>
<atag>123123</atag>
</this_tag>"#;
let mut data: Thistag = from_str(&s).unwrap();
data.atag = String::from("abc");
let newxml =to_string(&data).unwrap();
println!("{}",newxml);
}
```

还有 distroless
