Difference Between assert and require in Scala - Baeldung C.this, where C references a class. Scalactic Also, be aware that this is not entirely Scala's fault; nominal subtyping and whole-module type inference are fundamentally at odds with each other, and the designers of Scala chose to favor the former over the latter for the sake of Java compatibility, while the "purer" statically typed functional languages were mostly designed with the opposite choice in mind. Asking for help, clarification, or responding to other answers. Some engineers at Google have come to the conclusion that using required does more harm than good; they prefer to use only optional and repeated. Then we handle generated exceptions The signature doesn't say that. It had no major release in the last 12 months. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, The question is, why a String is valid type for the second argument while the signatures says it has to be a function 'message: => Any'. As you can see, each protobuf field becomes a member in the generated case class. When they are parsed, the runtime type would be a Vector. However with normal call convention the list.size part must be evaluated before the method is called - which might be wasteful. Why are there no snow chains for bicycles?
