Prerequisite
|| To follow this tutorial,
* <div style="margin-left:1.27cm;margin-right:0cm;">You must have basic knowledge of any programming language</div>
* <div style="margin-left:1.27cm;margin-right:0cm;"><span style="background-color:#ffffff;">You should also have </span><span style="background-color:#ffffff;">'''Rust '''</span><span style="background-color:#ffffff;">installed on your system.</span></div>

<div style="color:#000000;">'''About Cargo'''</div>

||
* <div style="margin-left:1.27cm;margin-right:0cm;"><span style="color:#000000;">'''Cargo '''</span><span style="color:#000000;">is a </span><span style="color:#000000;">'''Rust build system'''</span><span style="color:#000000;"> and </span><span style="color:#000000;">'''package manager'''</span></div>
* <div style="margin-left:1.27cm;margin-right:0cm;"><span style="color:#000000;">Cargo handles the compilation process</span> and automates<span style="color:#000000;"> the building of </span>your project.</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">Cargo allows you to add and manage external libraries to your project</div>
* <div style="margin-left:1.27cm;margin-right:0cm;"><span style="color:#000000;">In the </span><span style="color:#000000;">'''Cargo.toml</span><span style="color:#000000;"> '''</span><span style="color:#000000;">file, you can list your dependencies.</span></div>
* <div style="margin-left:1.27cm;margin-right:0cm;">Complex '''Rust '''programs need these '''dependencies''' to develop '''Rust projects'''<span style="color:#252525;">.</span></div>

|- style="border:1pt solid #252525;padding:0cm;"
|| '''Slide:'''

'''Cargo commands'''
|| <div style="color:#000000;">Let’s begin understanding the commands first.</div>
* <div style="color:#000000;margin-left:1.905cm;margin-right:0cm;">To create a Cargo project use '''cargo new project name'''</div>
* <div style="color:#000000;margin-left:1.905cm;margin-right:0cm;">To compile, use '''cargo build''' inside the created project.</div>
* <div style="color:#000000;margin-left:1.905cm;margin-right:0cm;">To run, use '''cargo run''' inside the project</div>

<div style="color:#000000;"></div>
|- style="border:1pt solid #252525;padding:0cm;"
|| <div style="color:#000000;">Open Visual code editor</div>

Click on it to open the file.

<span style="color:#000000;">All the code has to be run using this particular file </span><span style="color:#000000;">'''main.rs.'''</span>

<div style="color:#000000;">By default, we can see a hello world program on the right panel.</div>
|- style="border:1pt solid #252525;padding:0cm;"

<span style="color:#000000;">Save the file by pressing </span><span style="color:#000000;">'''Ctrl + S.'''</span>

<div style="color:#000000;">Let us compile and run the program.</div>
|- style="border:1pt solid #252525;padding:0cm;"

Make sure that we are inside the cargo project .i.e '''helloworld'''
|- style="border:1pt solid #252525;padding:0cm;"
| style="color:#000000;" | '''> cargo build'''
|| <span style="color:#000000;">In the terminal. type </span><span style="color:#000000;">'''cargo build '''</span><span style="color:#000000;">to compile the Cargo project.</span>

<div style="color:#000000;">When successfully compiled, we see a finished message.</div>

|- style="border:1pt solid #252525;padding:0cm;"
| style="color:#000000;" | '''Point to the output'''

<span style="color:#000000;">We can see both the text </span>messages<span style="color:#000000;"> as output.</span>
|- style="border:1pt solid #252525;padding:0cm;"

|| 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.
|- style="border:1pt solid #252525;padding:0cm;"

<div style="color:#000000;">This is where we can write all the project related information like name, version, authors, edition.</div>

<div style="color:#000000;">We can even mention dependencies which the project depends upon.</div>
