Associated Functions

Associated functions  از کلمه کلیدی self استفاده نمی‌کنند و با استفاده از سینتکس :: فراخوانی می‌شوند. با این حال، هنگام فراخوانی توابع مرتبط در متدهایی که از self استفاده می‌کنند، '.' بجای آن از سینتکس '::' استفاده می‌شود: 

impl Product {
    fn new(name: String, price: f32) -> Product {
        Product {
            name,
            price,
            in_stock: true,
        }
    }
}

اکنون، می‌توانیم یک نمونه محصول را با استفاده از تابع جدید مرتبط ایجاد کنیم:

fn main() {
    let book = Product::new(String::from("Book"), 30.0);
}
