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

  - Variables in Rust are, by default, immutable. Immutable variables can be shadowed, but never changed.

  - You can make a variable mutable with the `mut` keyword in its `let` statement.

  - Once mutable, you can change the value of a variable with assignment (e.g., `x = 5;`) and mutation operators (e.g., `x += 2;`).

  - Mutation is almost always necessary to perform iteration.

  - A `while` expression is like an `if` expression, but continues to evaluate the body as long as the condition remains true.

  - You can nest loops inside each other to create more powerful loops.

  - You can use `let` to declare variables without assigning, though you probably don’t want to.
