出于解释型编程语言的习惯，我想根据它们的键重写许多值。我假设我会将所有信息存储在为这个项目准备的结构中。所以我开始迭代：

struct Container {
    x: String,
    y: String,
    z: String
}
impl Container {
    // (...)    
    fn load_data(&self, data: &HashMap<String, String>) {
        let valid_keys = vec_of_strings![ // It's simple vector with Strings
            "x", "y", "z"
        ] ;
        for key_name in &valid_keys {
            if data.contains_key(key_name) {
                self[key_name] = Some(data.get(key_name);
                // It's invalid of course but
                // I do not know how to write it correctly.
                // For example, in PHP I would write it like this:
                // $this[$key_name] = $data[$key_name];
            } …
