Exploring Rust: Notes from a Beginner's Journey

This blog serves as my personal notes as I read through The Rust Programming Language book available on the official Rust website. Consider it a condensed version of the official guide, tailored for easy reference.

If you've installed Rust using rustup, the Rust book is also available offline. You can access it using the command:

rustup doc --book

At the time of writing this blog, I am using Rust version:

rustc 1.80.1 (3f5fd8dd4 2024-08-06)

Why Rust?
Rust is known for its speed, thanks to its lack of a garbage collector
. Most common programming errors are caught during the compilation 
stage, significantly reducing both syntactical and logical issues. 
However, achieving the desired program outcome still depends on the 
logic you implement—so if something doesn't work as expected, 
don't blame Rust!
Tools in Rust
Here are some essential tools for working with Rust:
Cargo: Rust's package manager, similar to npm in JavaScript.
Rustfmt: A tool for automatic code formatting.
rust-analyzer: Provides code completion and inline error 
messages in IDEs.
Installing Rust on macOS
Follow these steps to set up Rust on macOS. For other operating 
systems, refer to the official Rust book.
Install Rust via rustup:
curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh
Install a linker:
xcode-select --install
Verify the Rust installation:
rustc --version  # Check Rust version
echo $PATH       # Confirm Rust is added to the PATH
Update or uninstall Rust as needed:
rustup update         # To update Rust
rustup self uninstall # To uninstall Rust
What's Next?
In the upcoming post, I’ll cover getting started with Rust, 
including running your first "Hello, World!" program.
Until then, signing off! See you in the next blog post of the 
Rust series. 🚀
