![]() To build and run it, simply execute cargo run. As you may guess, this program is the Rust version of " hello world!". fn is how to declare functions while the ! in println! is a macro. Like many other languages, Rust has a main function that will be run first. We will work on the src/main.rs file for the rest of this tutorial, so go ahead and open it. You should see two files in there: $ tree. Now navigate to the newly created directory and list its content. In my case I have decided to name my project "todo-cli" so I can run: $ cargo new todo-cli To start a new project, navigate to where you want your project to be created then simply run cargo new. Cargo is the Rust package manager, and to JavaScript developers it'll feel like npm or yarn. There, you will also find instructions to integrate the language with your favorite editor for a better experience.Īlong with the Rust compiler itself, Rust comes with a tool called Cargo. To do so please follow the instructions you find on the getting started page of the official Rust website. ![]() To get started, download Rust onto your computer. In that case you can omit to have it as a return. This means that we have to type semicolons (" ") ourselves unless it is the last statement of a function. Also as opposed to JavaScript, there's no AFI.This means that we will have to take care of variable types when the compiler isn't able to infer types for us. Some advice before we get started, from someone coming from a JavaScript background: We will store values as a collection of items and a boolean value representing its active state. You'll also need some knowledge of general programming concepts. We will work with the command line so some familiarity with it is necessary. I have decided to follow the long tradition of JavaScript apps and make a to-do app as our first project. What we will build in this hands-on tutorial I am not a master of the language myself, but with this tutorial I'll try to give you a practical approach to some concepts to help you dig in deeper. The learning curve for Rust is considered to be somewhat steep. But its design often makes it look and feel very “high-level”. It has no garbage collector, which makes its performance really good. ![]() Rust was designed by Mozilla and is considered a system programming language (like C or C++). It's also been voted the most loved programming language on StackOverflow's developer survey each year since 2016. Since its first open-source release in 2015, the Rust programming language has gained a lot of attention from the community. ![]()
