The Builder Pattern and Typestate Programming - Stefan Baumgartner - Rust Linz January 2023

Almost 30 years ago, the Gang of Four wrote about software design patterns. They were highly influential, and over the course of decades, the proposed patterns have been cited, reused, misused, thrown away, and found again, over and over. One of those patterns -- the builder pattern -- gained some popularity in Rust's libraries. Let's take a look at what does, why the builder pattern is such a great fit for Rust, and how we can use some of the unique features of Rust's type system to make them even better. -- Stefan Baumgartner works at Dynatrace.
