Adhere to Rust API Guidelines

Suggestion / Feature Request

Wherever possible, update code to adhere to API Guidlines

I'm going to suggest that we add this for the v0.4 milestone, it's a great suggestion and if it seems minor enough we should do it sooner than later.

@jhodapp sure that works for me. It may be that this will come up as something we periodically audit and maintain. I would say if nothing else one iteration of this type of update will need to be done prior to 1.0
