Learn the basics of Rust programming from scratch, starting with the syntax, then moving to the core components of Rust.

Become a Rust Professional

In this module, we’ll start with the basics of the Rust programming language, and learn the syntax, philosophy, and the anatomy of Rust. With that in hand, we’ll move to some of the more unique parts of Rust, such as expression-oriented programming, ownership, and its robust type system.
In the latter half of the module, we’ll work through some of the core components of Rust, such as references, memory management, mutability, traits, slices, and generics.

The Ultimate Guide to Rust Programming

So far, our programs have all had exactly one function in them, `main`. As we said, `main` is the entry point to our program. But `main` is also a boring function. It doesn’t take any parameters, and it doesn’t produce any result value (at least, not the way we’ve seen it so far).

We’re going to work on defining and calling new functions. Let’s rewrite our Hello World program, but this time using a basically useless helper function:
