To iterate over the fields of a struct in Rust, you can use a for loop and destructure the fields of the struct inside the loop. Here is an example of how you could do it:

rust iterate over struct fields

struct Point {
    x: i32,
    y: i32,
}

fn main() {
    let point = Point { x: 3, y: 4 };

    for (x, y) in &point {
        println!("The x coordinate is {} and the y coordinate is {}", x, y);
    }
}

This will print:

The x coordinate is 3 and the y coordinate is 4

If you want to get the field names as well as the values, you can use a match expression inside the loop, like this:

struct Point {
    x: i32,
    y: i32,
}

fn main() {
    let point = Point { x: 3, y: 4 };

    for (name, value) in &point {
        match name {
            "x" => println!("The x coordinate is {}", value),
            "y" => println!("The y coordinate is {}", value),
            _ => (),
        }
    }
}

This will also print:

The x coordinate is 3
The y coordinate is 4

Keep in mind that this technique only works if the struct has #[derive(Debug)] or #[derive(Clone)] attributes, since these attributes are required to get an iterator over the fields of the struct.
