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

Arrays provide a handy method, `len()`, which tells you how many items they contain. They also support an *indexing operator*. An array has a sequence of values, numbered 0, 1, 2, and up. Each of these numbers is known as the *index*. The indexing operator takes the index and gives you the value at its position. Note that, since indices start at 0, an array of size 5 would have indices 0, 1, 2, 3, and 4, but does not have index 5.

This program will print out all of the values in the array:
