After reading the Rust book and writing about my initial experiences, I wanted a small practical project to familiarize myself with the language. So, I decided to write a REST client library. This post shows, step-by-step, how my initial design was refactored to be more robust and easy-to-use. Traits and generics are key concepts in these refactorings. The intent is not to cover the internals of the library in detail and also the basic syntax of traits and generics is not covered here. The Rust Book chapter 10 is an excellent resource for the latter.
