Practical Client-side Rust for Android, iOS, and Web

The text discusses the use of Rust for writing CPU-intensive tasks in client SDKs across different platforms, including iOS, Android, and web applications. It highlights how Rust can be used to write code once and compile it for multiple platforms, offering better performance than Java/Kotlin or Swift/Objective-C. The author shares their experience of building a prime number-counting app using Rust for all three platforms, addressing the challenges faced in configuring Gradle and Xcode, creating bindings between Rust and target languages, passing complex data structures, and invoking platform-specific callbacks. The text also provides code examples and insights into the tools used, such as Corrosion Plugin for CMake, swift-bridge plugin for Cargo, wasm-bindgen, and wasm-pack. Overall, it emphasizes that Rust's cross-platform capabilities can be leveraged to improve performance in various applications like video games, photo editors, virtual and augmented reality, and facial recognition.
