Explore how to handle copying data in Rust structs and the importance of ownership rules. Learn to avoid inefficient duplication by using techniques like name shadowing while recognizing the impact on performance and best practices.

We'll cover the following...

Rust 1.40.0
fn main() {
    let fruit1 = Fruit {
        apples: 10,
        bananas: 5,
    };

    };
    let price = price_fruit(fruit2);
    println!("I can make {} cents", price);
}

We make a fruit1 variable, and move its ...
