The Rust Programming Handbook

Rust Syntax and Functions

In this chapter, we will dive deep into the foundational aspects of Rust programming, focusing on the language’s syntax and functions. Understanding these basics is crucial as they form the building blocks for more advanced Rust programming concepts. This chapter aims to provide a comprehensive overview of variable declarations, data types, functions, control flow constructs, and error handling in Rust. By the end of this chapter, you will have a solid understanding of how to write basic Rust programs, manipulate data, and handle errors effectively.

Rust is known for its strict and expressive syntax, which enforces safety and correctness in your code. By learning Rust’s syntax, you will not only write more reliable programs but also gain a deeper understanding of how Rust ensures memory safety and performance. We will start with the fundamental concept of variable declarations and mutability, exploring how Rust handles data storage and manipulation...

Functions in Rust

Functions are a core component of Rust programming. They provide the means to organize your code into reusable blocks. Functions encapsulate logic, making your code more modular, maintainable, and easier to understand. We will explore more function in Chapter 3, but I want to give you a quick overview now.

This section will explore Rust’s function syntax, parameter passing, return values, and how Rust’s ownership model impacts functions.

Function syntax

In Rust, functions are defined using the fn keyword, followed by the function name, a list of parameters, and the function body enclosed in curly braces. Functions can take zero or more parameters and return a value.

fn main() {
    println!("Hello, world!");
}
fn greet(name: &str) {
    println!("Hello, {}!", name);
}
fn add(a: i32, b: i32) -> i32 {
    a + b
}

Let’s break down the preceding example:

main is the entry point of a Rust...

Control flow constructs

Control flow constructs are essential in any programming language, as they allow you to dictate the flow of execution in your programs. Rust provides a variety of control flow mechanisms, including conditional statements (if and else), loops (loop, while, and for), and pattern matching (match). These constructs enable you to build dynamic and responsive applications by controlling how and when different parts of your code are executed.

if and else statements

Conditional statements in Rust allow you to execute code based on certain conditions. The most common conditional statements are if and else.

fn main() { 
    let number = 7; 
    if number < 5 { 
        println!("The number is less than 5"); 
    } else if number > 5 { 
        println!("The number is greater than 5"); 
    } else { 
        println!("The number is exactly 5"); 
    }
}

In this example, the if statement checks if number is less than...

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
