Solution: Making a Phone Book

Explore how to create a phone book application in Rust by defining enums and structs to manage contact data. Learn to store multiple entries in a vector and print them with a loop. This lesson helps you understand practical data management and output in Rust programming.

We'll cover the following...

Solution

This exercise is all about storing data in a list and printing your phone book. Here is the complete implementation of the problem. Let’s take a look at it!

Rust 1.40.0
enum PhoneType {
    Home, Work, Cell
}
struct Person {
    name: String,
    phone: String,
    phone_type: PhoneType,
}
impl Person {
    fn new(name: &str, phone: &str, phone_type: PhoneType) -> Self {
        Self {
            name: name.to_string(),
            phone: phone.to_string(),
            phone_type
        }
    }
    fn print(&self) {
        println!("{}", self.name);
        println!("{} ({})", self.phone, match self.phone_type {
            PhoneType::Home => "Home",
            PhoneType::Work => "Work",
            PhoneType::Cell => "Cell",
        });
        println!("");
    }
}
fn main() {
    let people = vec![
        Person::new("Jane & John Doe", "555-123-4567", PhoneType::Home),
        Person::new("Joseph Bloggs", "555-111-2222", PhoneType::Work),
        Person::new("Rowena Stevenson", "555-111-3333", PhoneType::Cell),
        Person::new("Marcus Mills", "555-111-4444", PhoneType::Cell),
        Person::new("Orson Richards", "555-111-5555", PhoneType::Cell),
    ];
    for person in people.iter() {
        person.print();
    }
}
