Protocols in Akka Typed

This lecture covers the implementation of protocols in Akka Typed, focusing on typing Akka actors to restrict ActorRef to sending the correct message types. It explains the process of adding type parameters to ActorRef, defining understood message types in traits, and removing context.sender. The lecture also demonstrates creating a minimal protocol, proper channels using algebraic data types, and modeling protocols with different message types. Additionally, it discusses running actor programs, handling typed responses, and summarizes the philosophy behind adding types to Akka actors.
