Welcome to the technical archive. This is my introduction to Rust โ€” a language that's changing how we think about systems programming.

Why Rust?๐Ÿ”—

Rust is a systems programming language that provides memory safety without garbage collection. It's blazingly fast, prevents segfaults, and guarantees thread safety.

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

Key Features๐Ÿ”—

1. Ownership System๐Ÿ”—

Rust's ownership system is its secret weapon. Every value has a single owner, and when that owner goes out of scope, the value is dropped.

fn main() {
    let s1 = String::from("hello");
    let s2 = s1; // s1 is now invalid
    println!("{}", s2); // This works
    // println!("{}", s1); // This would fail
}

2. Borrow Checker๐Ÿ”—

The borrow checker ensures no data races at compile time. You can have either:

  • One mutable reference, OR
  • Any number of immutable references

3. Zero-Cost Abstractions๐Ÿ”—

Rust's abstractions compile down to the same code you'd write by hand. Iterators, for example, are just as fast as manual loops.

let sum: i32 = vec![1, 2, 3, 4, 5]
    .iter()
    .filter(|x| *x % 2 == 0)
    .sum();

4. Great Tooling๐Ÿ”—

  • Cargo: Package manager and build tool
  • rustfmt: Code formatter
  • Clippy: Linter with helpful suggestions
  • rust-analyzer: IDE support

When to Use Rust๐Ÿ”—

  • Command-line tools
  • Web services (with frameworks like Axum or Actix)
  • Embedded systems
  • WebAssembly
  • Game engines

Getting Started๐Ÿ”—

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
cargo new hello_rust
cd hello_rust
cargo run

Join the revolution. Rust isn't just a language โ€” it's a paradigm shift.
