The Benefits of Using a Result Type

A result class is a simple structure that tells you whether or not this operation succeeded. The benefit of using the result type is that your function signatures become very explicit in telling you that this call that you're going to make, it could succeed or it could fail. In court, you shouldn't catch them. You should only catch them at the topmost level of your coal stack. And the only way you should react to them is to just lock what exactly happened and then crash the application.
