That is a very straight-forward API indeed. Thanks for the example! I think this is a good approach. We can figure out a good buffer size and document it clearly....

> implementation of `Read` Just making sure, but this is the `Write` impl right? I saw no `Read` impl in the draft PR AFAIR. Regardless, sounds like a good plan.

'PartialEq' and 'Debug' can be derived with '#derive[()]' usually. Try with those macro-derived traits. Let me know if anything causes problems along the way!

Fixed in #294

@black-eagle17 I want to do a patch release due to #293, so I've gone ahead and fixed this PR up. Hope that's alright.
