Concepts with real-world examples and small practical projects with Rust


Create a struct in Rust called **Product** with fields like **name**, **price**, and **quantity**. Then implement methods to calculate the total value of a given product based on the quantity in stock. ```rust struct Product { name: String, price: f64, quantity: u32, } impl Product { // Method for creating a new product fn new(name: String, price: f64, quantity: u32) -> Self { Product { name, price, quantity } } // Method to calculate the total value of the product based on the quantity in stock fn total_value(&self) -> f64 { self.price * self.quantity as f64 } } fn main() { let product = Product::new(String::from("Laptop"), 1000.0, 5); println!("Total value of {} in stock: ${}", product.name, product.total_value()); } ``` In this example, the struct Product has three fields: name (of type String), price (of type f64) and quantity (of type u32). Next, we implement an associated new() method to create a new instance of Product and a total_value() method that calculates the total value of the product by multiplying the price by the quantity in stock. In main(), we exemplify the use of the struct and the methods created.

I took this comment from user `fschmidt` from the website [<span style="color: blue;">saidit.net</span>](http://saidit.net) talking about the Rust language > Rust is yet another disgusting modern language.
