Rust is popular on Stack Overflow surveys because its ownership system guarantees memory safety without a garbage collector, preventing entire classes of bugs at compile time. Developers value the tooling like cargo for dependency management and the ability to write systems-level code that is both fast and safe.
// Rust's ownership model prevents data races at compile time
fn main() {
let s1 = String::from("hello");
let s2 = s1; // s1 is moved, not copied; s1 is invalid here
// println!("{}", s1); // Compile error: use of moved value
println!("{}", s2); // Works
}
