Rust stable?

Would be great to be able to run constellation on stable channel :)

At the moment it's:

   Compiling metatype v0.2.1

error: could not compile `metatype`

Agreed! If you're willing to take a look I'm happy to advise.

metatype and serde_traitobject are the blockers.

IIRC specialization should be okay to avoid. It's ptr_metadata and arbitrary_self_types that will be tricky/impossible without being unsound and risking miscompilation.

Thanks for all the effort you have put into Constellation, and for making it OpenSource.
I'm not sure I fully understand, but I think erased-serde is an alternative - appreciate any clarification or insight into whether that is correct?
