Installation and Configuration of Rust

Rust

J"Rust is like C++ went to therapy, learned about memory safety, and came back as the responsible adult in the programming world—minus the midlife crisis!"

 

Setting Up Rust: The Easy Way (No Sweat!)

Alright, so you’ve decided to take the leap into Rust—great choice! Now, before you start writing code that makes your computer feel like a superhero, let’s get Rust installed and ready to roll. 

1. Installing Rust 

Rust comes with a super handy tool called Rustup that makes installation a breeze. Follow these steps, and you’ll be coding in no time!

Windows 

1. Open a terminal (Command Prompt or PowerShell).
2. Run this magical command:

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   

3. Follow the on-screen instructions.
4. Restart your terminal and verify Rust is installed:

   rustc --version
   

macOS 

1. Open your terminal.
2. Type this and press enter:

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   

3. Follow the instructions.
4. Run this to ensure everything is working:

   rustc --version
   

Linux 

1. Fire up your favorite terminal.
2. Run:

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   

3. Follow the setup wizard.
4. Check if Rust is installed:

   rustc --version
   

2. Configuring Rust 

Now that Rust is installed, let’s tweak a few settings to make your experience even better.

Updating Rust 

Rust gets frequent updates, so keeping it fresh is a good idea:

rustup update

Setting the Default Rust Version 

Want to use a specific Rust version?

rustup default stable

Or, if you need an older version:

rustup install 1.65.0
rustup default 1.65.0

Adding Components 

Some Rust tools aren’t installed by default. Add them like this:

rustup component add clippy rustfmt

3. Testing Your Rust Installation 

Let’s write a simple Rust program to make sure everything is working. Create a new file called main.rs and add this:

fn main() {
    println!("Hello, Rustaceans!");
}

Now, compile and run it:

rustc main.rs
./main

If you see Hello, Rustaceans!, congratulations!  You’re ready to roll with Rust!
