如何在遍历Vector时从&String中复制字符串？

fn main() {
    let vector: Vec<String> = vec!["Hello".to_string(), "World".to_string(), "Rust".to_string()];
    let mut copied_vector: Vec<String> = Vec::new();

    for string_ref in &vector {
        let copied_string = string_ref.clone();
        copied_vector.push(copied_string);
    }

    for string in copied_vector {
        println!("{}", string);
    }
}
