Rust Programming

If you don't mind a quick review:

Another thing worth noting is that it's as if the proc macro literally injects a bit of source code in-line where you call derive. This means that if you are going to refer to any structs/crates/modules etc.. it makes things a lot easier to refer to them via their full path.

I since that someone doesn't know about putting their impls in a:

const _: () = {
}

Also, using quote!{} instead of quote!() will make your indentation life easier.

anyhow instead of thiserror in your API is...

Otherwise, good, if very basic, write-up.
