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

  - The `main` we’ve seen so far is one example of a function.

  - We can define multiple other functions.

  - We can call functions similar to how we call macros (for example, `println!`).

  - Functions may take parameters, which are passed in from the caller.

  - Function parameters can be used as variables inside the body of a function.

  - Functions may return results of different types.

  - By default, functions return the unit `()` type.

  - A function body is a block, and may end with an expression, which will be its result value.

  - Function parameters are scoped to the function body.

  - Blocks create scopes for variables defined inside of them.

  - `main` is a normal function, but has some special rules:
    
      - It cannot take any parameters.
    
      - It can only have some special result types.
