Go vs Rust

Performance, Safety, and Use Cases Compared

Go prioritizes developer productivity and concurrency for web services, while Rust ensures memory safety and performance for systems programming.

Choose Go for rapid development of network services and microservices where simplicity and concurrency matter; choose Rust for systems programming where memory safety without a garbage collector and maximum performance are critical. Go compiles to a single binary with a garbage collector, while Rust uses a borrow checker to guarantee memory safety at compile time with zero-cost abstractions.

// Go: Simple concurrency with goroutines
func worker(id int) {
    for i := 0; i < 5; i++ {
        fmt.Printf("Worker %d: %d\n", id, i)
    }
}

func main() {
    for i := 0; i < 10; i++ {
        go worker(i)
    }
    time.Sleep(time.Second)
}
// Rust: Memory safety via ownership and borrowing
fn main() {
    let s1 = String::from("hello");
    let s2 = s1; // Ownership moved, s1 is invalid
    // println!("{}", s1); // Compile error: use of moved value
    println!("{}", s2);
}
