Title Slide

Welcome to the Spoken tutorial on Hello World using Cargo.
Show Slide:

Learning Objectives

In this tutorial, we will learn how to
  • Create a cargo project
  • Write a Hello world rust program
  • Compile and Run the cargo project
Show Slide:

System Requirements

This tutorial is recorded using
  • Ubuntu Linux OS version 22.04
  • Rust version 1.80.0
  • Visual studio code version 1.19.0
Show slide:

Prerequisite

To follow this tutorial,
  • You must have basic knowledge of any programming language
  • You should also have Rust installed on your system.
Slide:

About Cargo

  • Cargo is a Rust build system and package manager
  • Cargo handles the compilation process and automates the building of your project.
  • Cargo allows you at add and manage external libraries
  • In the Cargo.toml file, you can list your dependencies.
  • Complex Rust programs need these dependencies to develop Rust projects.
Open Visual code editor Let us open the Visual Studio Code editor.
click on terminal and select New Terminal. In the menu bar, click on terminal and select New Terminal.

We can see a terminal window at the bottom.

Create direcotry MyRustProject

>mkdir Desktop/MyRustProject

>cd Desktop/MyRustProject

Let us create a directory MyRustProject on the Desktop.

In the terminal, type as shown to create a directory MyRustProject.

We will save all the Rust Projects in this directory required for this series.

Type

>cargo new helloworld

Type the command cargo new helloworld

A binary cargo application has been created.

Click File>> Open folder

Select hello folder under MyRustPRoject

Open the created project by clicking on the File menu in the menu bar and then Open folder.

Go to Desktop and then select MyRustProject.

Locate the helloworld folder.

Then click on the open button at the top right corner.

Click src folder> main.rs In the left panel, under the EXPLORER section, expand the project hello by clicking on it.

Click the src folder, and you can see that a file called main.rs is created.

Click on it to open the file.

All the code has to be run using this particular file main.rs.

By default, we can see a hello world program on the right panel.

Let us see the Rust program structure.
Highlight according to narration.

fn main() {

println!("Hello, World!");

}

Every Rust program starts with this `main` function.

Inside the curly braces `{ ... }` Println command prints the text hello world.

The semicolon `;` at the end indicates the end of the command.

Save the file by pressing Ctrl + S.

Let us compile and run the program.

Click on terminal> new terminal In the menu bar, click on Terminal and select New Terminal.

Make sure that we are inside the cargo project that is helloworld

> cargo build In the terminal, type cargo build to compile the Cargo project.

When successfully compiled, we see a finished message.

>cargo run As the project is compiled successfully, it’s time to run the project.

Then type cargo run

Point to the output Now we see Hello world! printed in the terminal.
Type

Println!(“Welcome to Rust Spoken Tutorial”);

Press Ctrl+s

Let us add one more print statement in the program.

In the code window, type a print statement “welcome to Rust spoken tutorial” as shown.

Press Ctrl+ S to save the file.

> cargo run In the terminal, type cargo run

We can see both the text messages as output.

After switching back, I directly did a cargo run without compiling the project again.

Did you notice that?

When we do a cargo run, the package manager will build again and run the project.

So going forward, we can directly use cargo run to build and run the project in one go.

Click on cargo.toml In the left panel, open the file Cargo.toml.

We see two sections namely package and dependencies.

This is where we can write all the project related information like name, version, authors, edition.

We can even mention dependencies which the project depends upon.

Show Slide:

Summary

This brings us to the end of this tutorial.

Let us summarize.

Slide:

Assignment

As an assignment,
  • Create a cargo project named assignment
  • Print - “ Welcome to Rust Assignment”
  • Compile and execute the project
  • Observe the output in the Terminal
Show Slide:

Thank you

Thank you for joining.
