• Router needs to register a trait factory in Router macros. This is for instantiating the server side API from RPC traits.
  • airframe-di: registerTraitFactory for Scala 3 #2449 Prepare a trait instantiation factory. Related to Add reflect ClassDef.apply and Symbol.newClass scala/scala3#14124 Quotes: generate arbitrary trait or class implementations scala/scala3#11685 https://github.com/pomadchin/tagless-derivation/blob/5e9dc24686033cb93088e4c42519f295204f72df/src/main/scala/cats/tagless/macros/macroInvariantK.scala
  • implmeent AirframeMacros.shouldGenerateTrait(Type) for Scala 3
  • airframe-grpc also needs this fix

For example, we need to:

def regiterTraitFactory[A] = ... (macro impl)

// If A is a trait, create a factory to instantiate A. Writing this type of macros is not yet supported in Scala 3.1.x
registerTraitFactory(Surface.of[A}, { (s: Session) => new A {}  })
