Seems rather well designed actually. Appears that you can even use length-delimited lists and stuff. I like it. I have a project where we have a compact binary encoding and I have to write documentation _and_ serde for it. This works for docs and deserialization so that’s good. I understand why serialization isn’t supported but I feel like there’s probably a clever API that allows inserting your own ser in. We’ll see. I might switch our internal thing this weekend to it.

Would be cool if you could generate a protocol diagram from this.
