Why Rust?

Rust has been Stack Overflow’s most loved programming language for several years running. Let’s explore what makes it special.

Memory Safety Without Garbage Collection

One of Rust’s most notable features is its guarantee of memory safety without using a garbage collector. This is achieved through its ownership system:

fn main() {
    let s1 = String::from("hello");
    let s2 = s1; // s1 is moved to s2
    // println!("{}", s1); // This would cause a compile error
    println!("{}", s2); // This works fine
}

Zero-Cost Abstractions

Rust provides high-level features without runtime overhead:

// Iterator implementation that compiles to efficient machine code
let numbers = vec![1, 2, 3, 4, 5];
let sum: i32 = numbers.iter()
                     .filter(|&n| n % 2 == 0)
                     .sum();
