Router macro does not compile

[ioleo]

Hi,

huge thanks for all the awesome libraries you maintain. I just upgraded my side project to sloth 0.6.3 and I'm getting the compile error from RouterMacro:

You need to specify the type parameter for the route method explicitly: sloth.Router.apply[java.nio.ByteBuffer, zio.Task](zio.interop.catz.asyncRuntimeInstance[Nothing](zio.interop.catz.implicits.rts)).route[<missing>](contactFormRpc)

However my code is (and always was) expicitly providing the type parameter:

val router = Router[ByteBuffer, Task]
  .route[ContactFormRpc](contactFormRpc)
  .route[NewsletterRpc](newsletterRpc)
// ...

where contactFormRpc, newsletterRpc are exacly of given type.

Any ideas what could be wrong? I'm using scala 2.13.6.

Hi @ioleo, thanks for raising this issue!

I feared that this could happen. This error was an idea to protect you from routing to a concrete class instead of a class/trait with abstract methods. Making it more explicit what interface you are exposing.

What I am assuming: contactFormRpc is of type ContactFormRpc and not a subtype of it. If you would change the type to something more concrete, it should start working. But anyhow, I will remove this warning, as it should not circumvent this use-case.

I have just reverted the commit introducing this check and I started the release of a new version 0.6.4, which should land on maven soonish.

Thanks. On 0.6.4 it compiles again. Just a bunch of refactorings more and hopefully everything will work at runtime aswell.

Awesome! Please let me know if there are any other issues.
