What are enums in Rust?

Enums in Rust are a type that can represent one of several possible values. They are used to define a type by enumerating its possible variants.

Can you give me an example of how to define an enum?

Sure! Here's a simple example:

enum Direction {
    North,
    South,
    East,
    West,
}

How do I use enums in a match statement?

You can use enums in a match statement like this:

let dir = Direction::North;
match dir {
    Direction::North => println!("Going North!"),
    Direction::South => println!("Going South!"),
    _ => println!("Going in another direction!"),
}

What are the benefits of using enums?

Enums provide type safety, making your code more readable and maintainable. They also allow you to group related values together.
