Exploring Rust for Mobile App Development | RustMeUp

One of the rising stars in the world of programming languages is Rust. Known for its emphasis on memory safety, concurrent programming, and improving performance, Rust has become a preferred choice among developers for building scalable and reliable systems. However, Rust is not limited to system development. With its powerful features and performance advantages, it is carving its own niche in mobile app development. This guide intends to provide comprehensive information on how Rust can be harnessed for mobile app development.

What is Rust?

Rust, developed by Mozilla, is a statically-typed, compiled language aimed at delivering highly performant and reliable systems. The language ensures memory safety without a garbage collector, which makes it stand out among other programming languages. Rust is syntactically similar to C++, but its designers have put a lot of emphasis on safety, particularly safe concurrency.

Why Use Rust for Mobile App Development?

Rust brings several enhancements to mobile app development. Here are some compelling reasons why Rust is being increasingly used for developing mobile apps:

Tight Control Over System Resources

Unlike languages which use garbage collection to manage memory, Rust provides direct control over system resources which enables precise control over memory usage. This tight control improves the efficiency and performance of the mobile applications.

Enhanced Safety

Rust places a lot of emphasis on safety. The language is designed to prevent null pointer dereferencing and buffer overflow, two common issues that can lead to serious application vulnerabilities.

Concurrency and Speed

Rust has excellent support for concurrent programming which is crucial for mobile applications that need to perform various tasks simultaneously. Additionally, Rust's speed is comparable to languages like C and C++, making it a good choice for developing fast, responsive mobile applications.


Rust can easily interoperate with other languages. This allows developers to leverage existing libraries and frameworks in their mobile development process, further boosting productivity and efficiency.

How to Get Started with Rust for Mobile App Development?

Getting started with Rust for mobile app development involves a few steps to set up the tools and environment:

  1. Install Rust: The first step is to install Rust on your machine. You can do this using rustup, the Rust toolchain installer. Rustup manages Rust versions and associated tools for you.

  2. Setup IDE: You can use Rust in several IDEs such as Visual Studio Code, IntelliJ IDEA, Eclipse, etc. Rust support can be added via plugins to provide features like auto-completion, type inference, and so on.

  3. Learn Rust Syntax: If you're new to Rust, start by learning the syntax of the language. The Rust programming book, often referred to as "The Book," is a great place to start. It gives an in-depth understanding of various aspects of the language.

  4. Start with a Basic App: Once you grasp the basics, start developing a simple app. It could be a simple calculator or a note-taking app. This will help you understand how to structure a mobile app project in Rust.

  5. Explore Mobile-Specific Libraries: Libraries such as Flutter and GTK can be used for developing mobile applications in Rust. Explore these libraries to better understand how to leverage them for your app development.

  6. Build, Test, and Iterate: Build a prototype of your app, test it exhaustively to ensure it runs smoothly, and use feedback to continuously improve the app.

Rust Learning Resources

There are multiple resources available to learn Rust. Here are a few:

  • The Rust Programming Language - This is the official book from the makers of Rust.
  • Rust By Example - This resource provides a collection of runnable examples.
  • Rustlings - This is a series of small exercises to get you used to reading and writing Rust code.

Future Scope Of Rust In Mobile App Development

With tech giants like Microsoft and Google showing interest in Rust to replace or supplement C and C++, the future of Rust in the realm of mobile app development looks promising. Rust's potential shines in areas like game development, VR applications, hardware-level programming, and of course, general mobile app development.

With Rust's ongoing improvements and updates, we can expect more libraries and tools that will enhance its capabilities for mobile app development further, making it a viable choice for even more projects in the future.


1. Can Rust be used for both Android and iOS app development? Yes, Rust can be used for both Android and iOS development. There are libraries available, like Flutter, which provide cross-platform support.

2. Is it easy to learn Rust? While Rust has a steep learning curve compared to some languages, its active and supportive community, as well as abundant resources, makes it easier for motivated learners to learn.

3. Can Rust replace Java for Android app development? While Rust offers several advantages over Java, particularly regarding performance and safety, Rust and Java serve different niches. In some situations, especially when low-level resource management or high performance is a crucial factor, Rust could be a superior choice.

4. Is Rust good for backend development? Rust is excellent for backend development. Organizations like Dropbox have used Rust for backend development because of its high-performance capabilities.

5. Can you write an iOS app in Rust? Yes, Rust can be used to write iOS applications. However, it's worth noting that developing iOS applications in Rust will likely still involve working with Swift and Objective-C for certain aspects of your application.

Rust, with its excellent features, safer concurrency, and modern tooling, is an excellent choice for mobile app development. If safety, speed, and high performance are critical to your mobile app, then Rust could be the optimal language for your next project.
