The switch-hal crate just extends embedded-hal by a bit (hah!) -- but I find it very useful, for it provides clean "on"/"off" semantics for what is otherwise merely "high"/"low", and thus dependent on the actual wiring (both LEDs and buttons are just as easy to wire either way).
It's not used a lot (crates assume active-low instead), but I hope that this changes once it is more visible through here.
