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

I mentioned that an `if` is an expression. And if you remember from *Anatomy of Rust*:

> An expression is evaluated to a value of a specific type

So far, every `if` expression we’ve had evaluates to unit. However, we can have it evaluate to something else, with the following restriction:

  - There must be an `else` at the end

  - Each block for each `if`, `else`, and `else if` in the expression must evaluate to the same type

For example, this code is good:
