We learn about the Type State pattern in this video and combine it with the Builder pattern to convert runtime errors into compile-time errors. By implementing multiple States, we ensure consistent behavior in our method properties. Additionally, we explore using Phantom data when the type state requires no data. The Type State Builder pattern enhances the Request Builder by incorporating compile-time checks for URL setting and method property default, thereby improving code reliability. Through an example in Rust, we demonstrate how implementing the Type State pattern helps avoid runtime exceptions by ensuring that the build method is only called when the URL has been set. This involves creating two types - NoURL and URL - to represent the presence or absence of the URL property in the Request Builder.
