@ahl i'm not sure this is actually testing what i'd hoped to test. would be good to get your eyes on it.

for example i haven't patched progenitor-client, which is probably an issue

Nope! You'll have to run cargo xtask generate

Nope! You'll have to run cargo xtask generate

I did run that locally- didn't see any changes. Which was surprising

[danieleades]

@ahl i'm still not seeing any changes to code generation when running cargo xtask generate

[danieleades]

got it. had to explicitly patch typify as well.

as you can see the changes are fairly minimal, and they make the cloning explicit rather than implicit (as well as removing a couple of thousand lines of code)
