Use serde derive instead?

Hmm. This would simplify the code, but it would also increase the number of build-dependencies and the time required to compile them.

If I were writing this code from scratch, I would use typically use #[derive]. But since the manual impls are already written, and aren't much of a maintenance burden, I don't see much reason to switch to #[derive].
