Gain insights into Rust programming fundamentals, explore its syntax, ownership, and type system, and delve into core components like memory management, traits, and generics to enhance your skills.

Rust is quickly becoming one of the most popular languages. With a strong basis as a systems and embedded language, its clean design and ergonomics makes it an emerging choice for general purpose programming tasks as well. This course will be your guide to the fundamentals of programming and Rust. Whether you have no experience or want to learn a new language, this is the place to start.

In this course, you’ll start off with the basics of the Rust programming language, learning the syntax, the philosophy of the language, and the anatomy of Rust. With that in hand, you’ll move onto some of the more unique parts of Rust, such as expression-oriented programming, ownership, and its strong type system.

In the latter half of the course, you’ll work through some of the core components of Rust such as references, memory management, mutability, traits, slices, and generics.

By the time you finish, you’ll have the foundations in place to learn more advanced concepts and take your Rust programming to the next level.

The Ultimate Guide to Rust Programming

When introducing `for` loops, we mentioned that you can always use a `while` loop instead of a `for` loop. That’s pretty tricky to do without `break`. However, with `break`, it’s much easier. The basic idea is that we want to `break` as soon as we encounter a `None`.

fn main() {
    let mut iter = 1..10;
    while true {
        match iter.next() {
            None => break,
            Some(x) => println!("{}", x),
        }
    }
}


Doing this generates a warning:

```text
warning: denote infinite loops with `loop { ... }`
 --> src/main.rs:3:5
  |
3 |     while true {
  |     ^^^^^^^^^^ help: use `loop`
  |
```

Without `break`, the concept of an infinite loop is pretty useless: it just does things forever. However, now that we have `break`, we have a way of exiting an infinite loop. Instead of using `while true`, the recommended way of writing an infinite loop is to use the `loop` keyword.

**Exercise** Modify the program above to use the `loop` keyword.

Remember how we said that `continue` was nice, because it let us avoid indenting our code too much? Well, it would certainly be nice to do the same thing here. Let’s demonstrate one more cool trick we have with `break`, and then we’ll explain why it works:
