What are some examples of using traits in Rust?

In Rust, traits are used to define shared behavior. For example, the Iterator trait allows you to create custom iterators.

Can you give me a specific code example of a trait implementation?

Sure! Here's a simple example:

trait Speak {
    fn speak(&self);
}

struct Dog;

impl Speak for Dog {
    fn speak(&self) {
        println!("Woof!");
    }
}

fn main() {
    let dog = Dog;
    dog.speak(); // Outputs: Woof!
}

What are the benefits of using traits in Rust?

Traits promote code reusability and abstraction, allowing different types to share common behavior without inheritance.

How do traits differ from interfaces in other languages?

Traits in Rust can provide default method implementations, while interfaces in languages like Java require all methods to be implemented by the class.
