Rust

since 2010

Fast, safe, no compromises

Created by Graydon Hoare (Mozilla)

Rust gives you control over every byte of memory — without a garbage collector and without the undefined behavior that plagues C and C++. Its borrow checker is a novel idea: it proves at compile time that your program is memory-safe. The result is systems-level software that is both blazingly fast and provably correct.

// Key Features

Memory Safety
The borrow checker eliminates null pointers, dangling references, and data races — at compile time.
Zero-Cost Abstractions
High-level code that compiles down to machine code as fast as hand-written C. You don't pay for what you don't use.
Fearless Concurrency
The type system prevents data races at compile time. Write concurrent code with confidence.
No Runtime / GC
No garbage collector means predictable performance. Essential for games, OS kernels, and embedded systems.

// Code Example

safe-counter.rs
use std::sync::{Arc, Mutex};
use std::thread;

fn main() {
    // Arc = atomic reference counting (shared ownership)
    // Mutex = mutual exclusion (no data races)
    let counter = Arc::new(Mutex::new(0));
    let mut handles = vec![];

    for _ in 0..10 {
        let c = Arc::clone(&counter);
        let handle = thread::spawn(move || {
            let mut num = c.lock().unwrap();
            *num += 1;
        });
        handles.push(handle);
    }

    for h in handles { h.join().unwrap(); }
    println!("Result: {}", *counter.lock().unwrap());
    // → Result: 10 (always, guaranteed)
}

// Strengths

  • ✓Memory safe without GC
  • ✓C/C++ level performance
  • ✓Excellent error messages
  • ✓Strong type system
  • ✓Voted most loved language 8 years running

// Limitations

  • ✗Steep learning curve (borrow checker)
  • ✗Slower compile times
  • ✗Smaller ecosystem than Python/JS
  • ✗Verbose for simple tasks
