Contents and Example Usage
Typed identifiers allow compile-time checking that an identifier that is passed into a function or object is of the correct type, which is not the case with "untyped" String, Long or UUID types.
Guid is a space/cpu efficient and type safe replacement for java.util.UUID
val userGuid: Guid[User] = Guid.randomGuid val user: User = new User(userGuid, firstName, lastName)
Id can be used for typed identifiers (e.g. rdbms auto-increment ids).
val userId: Id[User, Long] = Random.nextLong val user: User = new User(userId, firstName, lastName)
Both Guid and Id can be used in conjunction with type aliases:
type UserGuid = Guid[User] type UserId = Id[User, Long] case class User(guid: UserGuid, id: UserId, firstName: String, lastName: String)
