Struct update syntax ? [rustlings]

[rwobben]

I have this :

fn create_order_template() -> Order {
    Order {
        name: String::from("Bob"),
        year: 2019,
        made_by_phone: false,
        made_by_mobile: false,
        made_by_email: true,
        item_number: 123,
        count: 0,
    }
}

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn your_order() {
        let order_template = create_order_template() {
            name: String::from("Hacker in Rust")
        }

but how can I update the name with the struct update syntax

maybe this is what you want:

let mut order_template = create_order_template();
order_template = Order {name: String::from("Hacker in Rust"), .. order_template};

this topic is in the rust book:

Thanks,

The stupid test is still failing :

fn your_order() {

       let order_template = create_order_template(); 

       your_order = Order {

           name : String::from("Hacker in Rust"),

           .. order_template

       };

       assert_eq!(your_order.name, "Hacker in Rust");
