implementing Implicitly Converting Nested Case Classes in Scala 3.2.1
I've spent hours debugging this and I'm working on a project and hit a roadblock. I'm working with issues with implicit conversions when dealing with nested case classes in Scala 3.2.1. I have a case class structure where one case class contains another as a field, and I'm trying to define an implicit conversion for the nested class. When I attempt to use the outer case class, I get a compilation behavior that states, `missing parameter type for method to in object Predef`. I defined my case classes as follows: ```scala case class Address(street: String, city: String) case class User(name: String, address: Address) ``` Now, I want to create an implicit conversion that allows me to convert a tuple into a `User` object. Here’s the implicit conversion I’ve defined: ```scala object Conversions { import scala.language.implicitConversions implicit def tupleToUser(tuple: (String, (String, String))): User = { val (name, (street, city)) = tuple User(name, Address(street, city)) } } ``` I expected that this conversion would work seamlessly, but when I try to use it like this: ```scala import Conversions._ val user: User = "John Doe" -> ("123 Elm St", "Springfield") ``` I'm greeted with the behavior mentioned above. I've tried explicitly specifying the parameter types in the implicit conversion method, but it doesn't seem to help. Could the scenario be related to how Scala 3 handles implicits differently from Scala 2? Any guidance on how to resolve this or best practices for working with implicit conversions in nested structures would be greatly appreciated. For context: I'm using Scala on Windows. Thanks for any help you can provide! The project is a desktop app built with Scala.
