Product Types

Input:

type Person
  name: Text
  age: Integer
  admin: Boolean

Output:

case class Person(
  name: String,
  age: Long,
  admin: Boolean
)

Products become Scala 3 case classes.

Validators

def validatePerson(x: Person): Either[String, Person] =
  val errors = List.newBuilder[String]
  val result = errors.result()
  if result.nonEmpty then Left(result.mkString("; "))
  else Right(x)

Validators return Either[String, Person].
