Health Statistics

You’re working on implementing a health-monitoring system. As part of that, you need to keep track of users’ health statistics.

You’ll start with some stubbed functions in an impl block as well as a User struct definition. Your goal is to implement the stubbed out methods on the User struct defined in the impl block.

Copy the code below to https://play.rust-lang.org/ and fill in the missing methods:

// TODO: remove this when you're done with your implementation.

struct User {
    name: String,
    age: u32,
    weight: f32,
}

impl User {
    pub fn new(name: String, age: u32, weight: f32) -> Self {
        unimplemented!()
    }

    pub fn name(&self) -> &str {
        unimplemented!()
    }

    pub fn age(&self) -> u32 {
        unimplemented!()
    }

    pub fn weight(&self) -> f32 {
        unimplemented!()
    }

    pub fn set_age(&mut self, new_age: u32) {
        unimplemented!()
    }

    pub fn set_weight(&mut self, new_weight: f32) {
        unimplemented!()
    }
}

fn main() {
    let bob = User::new(String::from("Bob"), 32, 155.2);
    println!("I'm {} and my age is {}", bob.name(), bob.age());
}

#[test]
fn test_weight() {
    let bob = User::new(String::from("Bob"), 32, 155.2);
    assert_eq!(bob.weight(), 155.2);
}

#[test]
fn test_set_age() {
    let mut bob = User::new(String::from("Bob"), 32, 155.2);
    assert_eq!(bob.age(), 32);
    bob.set_age(33);
    assert_eq!(bob.age(), 33);
}
