Description of Changes

Flattens BuiltinType into AlgebraicType.
See note below on BSATN ABI breakage.

API and ABI

  • This is a breaking change to the module ABI
  • This is a breaking change to the module API
  • This is a breaking change to the ClientAPI
  • This is a breaking change to the SDK API

If the API is breaking, please state below what will break

BSATN does not change for AlgebraicValue but it does for AlgebraicType as this includes tags for each variant so the indirection of BuiltinType was present in the codec but is no longer.

LGTM.

Note: We don't have a way to assert the changes in the bindings are correct

Question: Because the type is structural is not the order significant?
