Introduction

Welcome to the Rust Programming Course! If you're here, it’s because you've heard about Rust—a transformative programming language celebrated for its safety, performance, and reliability. According to the Stack Overflow Developer Survey, Rust is one of the most admired programming languages in today’s tech landscape. Its strong system capabilities make it perfect for building efficient and reliable software in domains such as systems programming, web development, and more.

Major tech companies like Mozilla, Microsoft, and Dropbox rely on Rust for their high-performance projects, and the market demand for skilled Rust developers is rapidly growing.

I'm Priyanka Yadav, your instructor on this journey into Rust programming. Whether you're an absolute beginner or an experienced coder looking to expand your skillset, this course is designed to take you from basic Rust syntax to advanced programming concepts. Each module comes with hands-on labs that encourage experimentation and learning by doing, ensuring you gain the confidence and skills required for professional Rust development.

Below is an overview of what we will cover.

Getting Started with Rust

Kick off your journey by setting up your development environment effortlessly. In this section, we introduce Cargo—Rust’s powerful package manager and build system—which simplifies project management and dependency handling.

Rust Basics

Begin your programming experience with Rust by writing your first program and exploring the language's unique syntax. In this module, you'll cover essential topics such as:

• Variables and data types
• Control flow
• Immutable versus mutable variables

Consider the following example that demonstrates immutability in Rust:

fn main() {
    let y = 10;
    println!("The value of y is: {}", y);
    // The next line will cause a compilation error because 'y' is immutable
    y = 20;
    println!("The value of y is: {}", y);
}

This code will produce an error similar to:

error[E0384]: cannot assign twice to immutable variable `y`
  |
2 |     let y = 10;
  |         - first assignment to `y`
4 |     y = 20;
  |     ^^^^^^^ cannot assign twice to immutable variable

Functions and Memory Management

In this module, you will explore how functions work in Rust, including parameter handling and Rust’s distinctive approach to memory management. Key concepts include:

• Ownership
• Borrowing
• Lifetimes

These topics are essential for writing secure and efficient Rust code.

Collections and Error Handling

Learn how to work with common data structures in Rust such as structs, enums, vectors, and hashmaps. This section also covers Rust’s error handling and logging mechanisms.

For example, the code snippet below defines a struct and implements the Display trait:

use std::fmt;

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

impl fmt::Display for Point {
    fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
        write!(f, "({}, {})", self.x, self.y)
    }
}

fn main() {
    let p = Point { x: 5, y: 10 };
    println!("Point: {}", p);
}

Another example demonstrates how to create a HashMap and insert elements:

use std::collections::HashMap;

fn main() {
    // Create a HashMap to store student grades
    let mut student_grades: HashMap<String, i32> = HashMap::new();
    student_grades.insert(String::from("Alice"), 85);
}

Code Organization and Advanced Techniques

This module will guide you through organizing your Rust projects using packages, modules, and crates. Furthermore, you'll learn how to build advanced command-line tools with Rust’s extensive libraries, leading to clean, maintainable, and scalable applications.

Concurrency and Debugging

Rust shines when it comes to supporting concurrency. In this section, you’ll explore:

• Concurrency features
• Asynchronous programming
• Debugging tools and strategies

Below is an example that integrates basic functions with concurrency principles:

fn util() {
    println!("This is a utility function");
}

fn main() {
    let x: i32 = 5;
    println!("The value of x is: {}", x);

    let y: i32 = 10;
    println!("The value of y is: {}", y);

    let z: i32 = x + y;
    println!("x + y = {}", z);

    util();
}

Advanced Concepts

Delve into Rust's advanced features such as traits, generic types, and smart pointers. You will also get hands-on experience with network programming, file handling, and integrating Rust with WebAssembly. The following example shows how to create an enum with recursive types, using Box for heap allocation:

#[derive(Debug)]
enum List {
    Cons(i32, Box<List>), // Recursive variant using Box to allocate on the heap
    Nil,
}

fn main() {
    let list: List = List::Cons(1, Box::new(List::Cons(2, Box::new(List::Nil))));
    println!("{:?}", list);
}

Capstone Project

In the final module, you will have the chance to apply everything you’ve learned by working on a comprehensive capstone project. This project will integrate the concepts from all modules, ensuring you have practical experience in both simple and complex Rust programming projects.
