> Even if your pretty familiar with rust you still have to break it apart and explicitly place the types in the "Let" statements to know the intermediate types in order to look up the method documentation.

Maybe this is just me misreading your phrasing, but why would you actually have to break it apart into `let` statements? You can look up the types without modifying the program. Or are you talking about asking the compiler for the types with the `let _: () = ...` (or similar) trick? At that point you can just ask an IDE, also without modifying the program.
