`cargo check` is what my editor runs automatically to find type errors, that runs automatically on every save. It doesn't allow me to actually "check" that the application does what I want it to. I run `cargo run/build` when I need to "humanly" test the application, and waiting 20 seconds for it is pretty bad. But then I come from a dynamic application development background (mostly Clojure), so maybe I do have a pretty unfair view on how fast I should be able to make a change and see the effects (sub second is the usual wait time in Clojure land).
