Creating a Ruby Gem with Rust

In this post you will learn how to create a Rust library and access it with a Rubygem.I’m a big fan of the Ruby programming language, it’s been a one of my primary programming languages for the last 12 years. It’s an extremely expressive language that really lends itself to writing elegant and easy to read code. One drawback however, is it’s performance. In fact it’s probably the biggest criticism of the language that I hear. If you are writing code where performance is critical, then Ruby might not be the right tool for the job. This doesn’t necessarily mean you have to switch technologies entirely, or create another microservice, you can in fact write a native library and interface it with Ruby.
