Details

We all love Ruby for its expressiveness. It's perfect for high-level domain modelling and its rich syntax allows us to build complex applications that are straightforward to reason with and maintain. But what if you need to skip the performance overhead of the Ruby interpreter and run some optimised native code? Or use a third party tool or library that's written in a lower-level language?

In this talk, Sean Handley takes us through the process of building bindings in Ruby using FFI, unlocking the power of lower-level languages like C and Rust without giving up Ruby's expressive syntax. He'll discuss how computers actually execute subroutines, what libFFI does behind the scenes to enable the Ruby interpreter to call native functions, and explain the features of Ruby's FFI gem with some real-world examples.

About the speaker
Sean Handley is a senior software engineer at Stuart, a last-mile delivery company based in Paris. He mainly writes code in Ruby and Elixir but loves to experiment with other languages.
