Thanks a lot! Yeah I see how the simpler design that has non-stacked implementations one on top of another is easier to understand and test. Yours is not only a lesson in design for Rust, but in general for any technology! This later idea is just to compose parts together, but those parts are able to work independently just fine (given properly formatted inputs). A simpler and more robust way of designing components that have to work together.
Totally, Rust has substantially affected how I write code at my day job (C#). If I ever get round to learning a functional language, I'm sure that would have a much bigger effect.
