Write a Rust program to sort a vector of objects based on a specific property.

Question

Sure, here is a Rust program to sort a vector of objects based on a specific property:
Rust
struct Person {
    name: String,
    age: i32,
}
fn sort_by_age(people: andmut Vecandlt;Person>) {
    people.sort_by(|a, b| a.age.cmp(andb.age));
}
fn main() {
    let mut people = vec![
        Person { name: "Alice".to_string(), age: 20 },
        Person { name: "Bob".to_string(), age: 30 },
        Person { name: "Carol".to_string(), age: 10 },
    ];
    sort_by_age(andmut people);
    println!("The people sorted by age:");
    for person in people {
        println!("{:?}", person);
    }
}
This program first defines a struct called Person that has two properties:
name and age. The sort_by_age function takes a mutable reference to a
Vec of Person and sorts the vector by the age property. The
main function of the program creates a vector of Person objects and then calls the
sort_by_age function with the vector as input. The result of the function call is then printed to the console.
To run the program, you can save it as a file called sort_by_age.rs and then compile it using the following command:
Code snippet
rustc sort_by_age.rs
Once the program is compiled, you can run it using the following command:
Code snippet
./sort_by_age
This will print the following output to the console:
Code snippet
The people sorted by age:
Person { name: "Carol".to_string(), age: 10 }
Person { name: "Alice".to_string(), age: 20 }
Person { name: "Bob".to_string(), age: 30 }
