Using Structs in Rust

Level: medium (score: 3)

💡 Individual exercises are great, but nothing beats building a real-world app with Rust. Check out our Rust Intro Cohort Program!

Update the Person struct to model a person with name, age, and email fields. Implement a method greet that returns a greeting string using the struct's fields.

Example

Given a Person instance with the following fields, it should return the following greeting:

let person = Person {
    name: String::from("John"),
    age: 30,
    email: String::from("john@example.com"),
};

let greeting = person.greet()

This will print: Hello, my name is John and I am 30 years old. You can contact me at john@example.com

strings structs methods

Code

struct Person {
    // Define fields for name, age, and email
}

impl Person {
    // Implement a method to return a greeting string
}

#[cfg(test)]
mod tests {
    use super::*;

#[test]
    fn test_person_greet() {
        let person = Person {
            name: String::from("Alice"),
            age: 28,
            email: String::from("alice@example.com"),
        };

// Test the greet method
        let greeting = person.greet();
        assert_eq!(
            greeting,
            "Hello, my name is Alice and I am 28 years old. You can contact me at alice@example.com"
        );
    }

#[test]
    fn test_person_greet_different_person() {
        let person = Person {
            name: String::from("Bob"),
            age: 45,
            email: String::from("bob@example.com"),
        };

// Test the greet method for a different person
        let greeting = person.greet();
        assert_eq!(
            greeting,
            "Hello, my name is Bob and I am 45 years old. You can contact me at bob@example.com"
        );
    }
}
