|-
|| Slide: Title
|| Welcome to the spoken tutorial on '''Printing Hello World using Cargo.'''

|-
|| Slide:

Learning Objectives
|| In this tutorial we will learn:

* How to create a '''Cargo project''' and
* Execute it.

|-
|| Slide: System Specifications
|| This tutorial is recorded using:

* '''Ubuntu Linux''' OS version 18.04
* '''Rust''' version 1.47.0
* '''Visual Studio Code''' version 1.45.0 ('''code editor''')

However you may use any other '''editor''' of your choice.

|-
|| Slide : Pre-requisites
||
* To practice this tutorial, you should be familiar with basic '''Linux commands.'''
* If not, please go through the prerequisite tutorials on this website.

|-
|| Slide: Why '''Cargo'''?
||
* '''Cargo '''is a '''Rust build system''' and '''package manager'''
* '''Rustaceans''' use '''cargo '''to manage their '''projects''' as it makes the '''developer'''’s life easier.

|-
|| Slide: What does '''Cargo '''do'''?'''
||
* '''Cargo '''takes care of '''building''' our '''code'''
* '''Downloading '''and managing '''libraries '''that our '''code '''depends on.
* Complex '''Rust '''programs need these '''dependencies''' to develop '''Rust projects'''.

|-
|| Slide: Create, Compile and Execute the '''Cargo '''Project
|| Let’s begin understanding the '''commands '''first.

* To create a '''Cargo project''' use '''cargo new project_name'''
* To '''compile''', use '''cargo build''' inside the created '''project'''.
* To '''run''', use '''cargo run '''inside the '''project'''.

|-
|| Press '''Ctrl+Alt+T '''keys
|| Open the '''terminal''' by pressing '''Ctrl,Alt''' and '''T''' keys simultaneously on the keyboard.

Ensure that you have '''root permissions''' to '''run''' the '''commands'''.

|-
|| Only Narration
|| Here onwards, please remember to press the '''Enter''' key after typing each '''command'''.

|-
|| <nowiki>[Terminal] Type:</nowiki>

cd Desktop/MyRustProject

<nowiki>[Enter]</nowiki>
|| Using '''cd command''' go to the '''Rust''' practice folder which we created earlier.

|-
|| <nowiki>[Terminal] Type: </nowiki>

'''cargo new sample_hello_world '''<nowiki>[Enter]</nowiki>
|| Now let us create a '''Cargo project''' named '''sample_hello_word'''

To do so, type the '''command''' as shown.

|-
|| <nowiki>[Terminal] Highlight:</nowiki>

Created binary (application) `sample_hello_world` package
|| A '''binary cargo application''' has been created.

|-
|| Open Visual Studio Code editor.
|| You may use any '''editor''' of your choice.

I will use '''Visual Studio Code editor '''for this demonstration'''.'''

|-
|| <nowiki>[Editor] </nowiki>

Welcome Page ->

Open Folder ->

sample_hello_world
|| Open the created '''project''' by clicking on the '''Open folder''' link in the '''Welcome page'''

Browse and locate the folder “'''sample_hello_world'''”.

Then click on the '''OK '''button at the top right corner.

|-
|| <nowiki>[Editor] </nowiki>

Click on '''SAMPLE_HELLO_WORLD'''
|| Under the '''EXPLORER''' section, expand the '''project''' folder “'''SAMPLE_HELLO_WORLD'''” by clicking on it.

|-
|| <nowiki>[Editor]</nowiki>

For respective names - show cursor in the left side pane
|| We see the '''src '''folder and a '''Cargo.toml''' file created inside the '''project folder'''.

|-
|| <nowiki>[Editor] </nowiki>Click on '''src'''

Point to '''main.rs'''
|| Click on the '''src''' folder to expand it.

We find '''main.rs''' file inside the '''src''' folder.

|-
|| <nowiki>[Editor] </nowiki>Click on '''main.rs'''
|| Open the file '''main.rs''' by clicking on it.

|-
|| <nowiki>[Editor - main.rs] </nowiki>

Highlight the code
|| We can see the '''hello world program''' written inside.

By default, when you create the '''cargo project''', it creates the '''main.rs''' file inside the '''src''' folder.

And a '''main function''' would be written by default.

|-
|| <nowiki>[Editor] </nowiki>Click on '''Cargo.toml'''
|| Open the file '''Cargo.toml''' from the '''project''' folder by clicking on it

|-
|| <nowiki>[Editor - </nowiki>'''Cargo.toml''']

Highlight the code
|| We see two sections namely '''package''' and '''dependencies.'''

|-
|| <nowiki>[Editor - </nowiki>'''Cargo.toml''']

Highlight the '''package''' section
|| This is where we can write all the '''project''' related information like '''name''', '''version''', '''authors''', '''edition.'''

|-
|| <nowiki>[Editor - </nowiki>'''Cargo.toml''']

Highlight the '''dependencies''' section
|| We can even mention the '''dependencies''' which the '''project''' depends upon.

|-
|| Switch to terminal
|| Switch back to the '''terminal.'''

|-
|| <nowiki>[Terminal] </nowiki>Type:

'''cd sample_hello_world '''

<nowiki>[Enter]</nowiki>
|| So the '''Cargo project''' is created now.

Navigate inside the '''cargo project sample_hello_world''' using the '''cd command.'''

|-
|| <nowiki>[Terminal] Type: </nowiki>

'''cargo build '''<nowiki>[Enter]</nowiki>
|| Now type the following '''command''' to build the '''Cargo project.'''

|-
|| <nowiki>[Terminal] Highlight: </nowiki>

'''Finished'''
|| When successfully '''compiled, '''we see a finished message.

|-
|| Only narration
|| If we encounter any error, it means we have not installed '''Cargo''' properly.

Please revisit the installation tutorial and install '''Cargo''' properly before continuing.

|-
|| <nowiki>[Terminal] Type: </nowiki>

'''cargo run '''<nowiki>[Enter]</nowiki>
|| As the '''project''' is '''compiled''' successfully, it’s time to '''run''' the '''project'''.

To '''run,''' type '''cargo run'''.

|-
|| <nowiki>[Terminal] Highlight: </nowiki>

'''Hello, world!'''
|| Now we see '''Hello world''' printed in the '''terminal'''.

|-
|| Only narration
|| With this we have come to the end of this tutorial.

Let’s summarize.

|-
|| Slide''': '''Summary''' '''
|| In this tutorial, we have learnt how to '''create, compile '''and''' execute''' a '''Cargo project'''.

|-
|| Slide: Assignment
|| As an assignment,

* Create a '''cargo project''' named '''rust-assignment'''
* Print - '''‘Welcome to Spoken Tutorials!’'''
* '''Compile '''and '''execute '''the '''project'''.
* Observe the output in the '''Terminal'''
