Introduction to Rust

Rust is a systems programming language that aims to provide high performance and reliability without sacrificing productivity and memory safety. It achieves this by enforcing strict ownership rules and type safety at compile time. Rust's design focuses on empowering developers to write safe and concurrent code with minimal runtime overhead. A key feature is the borrow checker, which prevents data races and memory errors by ensuring that only one mutable reference or multiple immutable references to data exist at a time. This makes Rust ideal for developing software where performance and safety are critical, such as operating systems, game engines, and real-time systems. For example, in a scenario where you need to manage memory manually, Rust's ownership system ensures that memory is freed when it is no longer needed, preventing common bugs like use-after-free or double-free. Here's a simple example illustrating Rust's ownership and borrowing: ```rust fn main() { let s1 = String::from("hello"); // s1 owns the string let s2 = &s1; // s2 borrows the string immutably println!("{}", s2); // This is allowed because s2 is an immutable borrow // let s3 = &mut s1; // Uncommenting this line would cause a compile-time error } ``` This code demonstrates Rust's borrowing system where `s2` is an immutable reference to `s1`, and trying to create a mutable reference `s3` while `s2` is in scope would result in a compile error.
