What are the differences between structs and classes in Rust?

In Rust, structs are used to create custom data types, while classes (or traits) are used for behavior. Structs are more about data, whereas traits define shared behavior.

Can you give me an example of a struct and a trait?

Sure! Here's a simple struct:

struct Person {
    name: String,
    age: u32,
}

And a trait could look like this:

trait Greet {
    fn greet(&self);
}

How do I implement a trait for a struct?

You can implement a trait for a struct like this:

impl Greet for Person {
    fn greet(&self) {
        println!("Hello, my name is {} and I am {} years old!", self.name, self.age);
    }
}

What are the advantages of using structs over classes?

Structs in Rust are more lightweight and provide better performance for data storage. They also enforce immutability by default, which can lead to safer code.
