Use the
Deprecated
type fromtfhe-versionable
for all the deprecated versions. This removes a bit of code in the backward_compat folders and will improve the error messages because most errors should happen at deserialization, before the call to the "upgrade" method.Sadly the
Deprecable
trait for the types that have deprecated versions is a bit hard to implement with a declarative macro, because the macro needs to handle types with generics (especially with "nested" generics like<Scalar: UnsignedInteger, C: Container<Element = Scalar>>
). I think it would require a proc-macro, but I don't know if its worth the price for a few impl (And I think it would be the same thing with impl ofNamed
)
