Rust 101: Write, Build, and Debug Your First Program

Step 1: Installing Rust

Rust can be installed from the official website using rustup, a command-line tool for managing Rust versions and associated tools.

Here’s how you can install Rust on various operating systems:

On Unix-based systems (like Linux and macOS):

Open a terminal and enter the following command:

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

On Windows:

Download and run rustup-init.exe from the rustup website. Then, follow the onscreen instructions.

Rustup will install the latest stable version of Rust. The installation also includes cargo, Rust’s package manager, and other essential tools.

Step 2: Verifying the Installation

You can verify your installation by reopening your terminal (or command prompt on Windows) and running:

rustc --version

You should see the Rust version number, commit hash, and commit date.
