Structs

Structs are one of Rust's fundamental building blocks for creating custom types. They allow you to group together related data under one type, making your programs easier to understand and maintain. In this challenge, you'll work with Rust structs by creating a simple structure to represent a Person.

A struct in Rust can have named fields with different data types. For example:

struct Book {
    name: String,
    author: String,
}

Once defined, you can create instances of the struct and access or modify its fields using dot notation.

Your Task

Your task is to define a struct called Person with the following fields:

name: A String representing the person's name.
age: A u8 representing the person's age.

You must also implement a function is_adult that takes a reference to a Person and returns true if the person's age is 18 or older, and false otherwise.

Requirements

Define a struct called Person with the fields name and age.
Implement the function is_adult to determine if a person is an adult (18 or older).
Make sure the struct and it's fields are public.
```
pub struct Book {
    pub name: String,
    pub author: String,
}
```
This will allow the tests to access the struct and its fields. Without this, the tests will fail.

Example Test

Here's how your code will be tested:

let john = Person { name: "John".to_string(), age: 20 };
assert_eq!(is_adult(&john), true);
 
let emily = Person { name: "Emily".to_string(), age: 15 };
assert_eq!(is_adult(&emily), false);

Hints

Use & to pass references to avoid unnecessary copies.
Use the age field directly in a comparison for the is_adult function.
