Building an Air Quality Measurement App with Rustler and Elixir

In this video, Code & Stuff demonstrates how to develop a non-trivial air quality measurement application utilizing Rustler for integrating Rust with Elixir. The tutorial navigates through starting Rustler, initializing a project, and reading measurements from an air quality sensor using Rust. The integration involves setting up a GenServer to manage state and employing Phoenix LiveView and PubSub to dynamically update and send sensor readings to the browser. Viewers are introduced to Rustler for creating native implemented functions (NIFs) and shown how to manage Bluetooth Low Energy (BLE) devices by wrapping a Rust crate. The video moves on to implementing a Phoenix LiveView module that displays the sensor readings in real-time on a webpage, providing a comprehensive example of combining the strengths of Rust and the Elixir ecosystem to build robust and interactive applications.
