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

A lot of Rust involves lots of special symbols. Let’s look at our "Hello, world\!" program again:

fn main() {
    println!("Hello, world!");
}


We have the left parenthesis, `(`, right parenthesis, `)`, left curly brace, `{`, right curly brace, `}`, semicolon `;`, and double quotes, `"`. Ignore the semicolon for now, we’ll discuss it a bit later. The others all come in pairs in our program:

  - Every left parenthesis has a matching right.

  - Every left curly brace has a matching right.

  - There’s no “left double quote” and “right double quote,” but there are two double quotes that form a pair.

This is pretty common in Rust. We use these special symbols to group stuff together. For example, the curly braces group together the body of the function. The second set of parentheses group the parameter list passed to the `println!` macro. And the double quotes group together the string parameter.

The other important part of all of this is that these pairs nest. In other words, you can put one pair of symbols inside another. And notice in the program above that we always close off the inner pair before closing the outer pair. In other words, the code above is correct, but this code is incorrect:
