1. trait JsonSchemas extends algebra.JsonSchemas

   

   Enriches JsonSchemas with two kinds of operations:

   Enriches JsonSchemas with two kinds of operations:

   - genericJsonSchema[A] derives the JsonSchema of an algebraic data type A; - (field1 :×: field2 :×: …).as[A] builds a tuple of Records and maps it to a case class A

   The data type description derivation is based on the underlying field and constructor names.

   For instance, consider the following program that derives the description of a case class:

   case class User(name: String, age: Int)
   object User {
     implicit val schema: JsonSchema[User] = genericJsonSchema[User]
   }

   It is equivalent to the following:

   case class User(name: String, age: Int)
   object User {
     implicit val schema: JsonSchema[User] = (
       field[String]("name") zip
       field[Int]("age")
     ).xmap((User.apply _).tupled)(Function.unlift(User.unapply))
   }
