In episode 95 of Thinking Elixir, we talk with Philip Sampaio to understand the Rustler Precompiled project he created and what problem it helps solve. The project helps lower the bar for using Rust libraries for NIFs in Elixir making it possible to see more libraries using Rustler in the future. He explains what prompted the work initially and how projects can benefit from it. We discuss what it means for internal company projects and especially for libraries. He explains how the project addresses the many architecture and platform combinations too. We end with learning about his sample CI project that shows us how to set up our own CI systems to use it.
