ActionPlan

public struct ActionPlan<State> : RunnableAction

Encapsulates external business logic outside of a reducer into a special kind of action.

   enum UserAction {

     static func loadUser(byId id: String) -> ActionPlan<AppState> {
       ActionPlan<AppState> { store in
         guard !store.state.users.hasValue(id) else { return nil }
         store.send(UserAction.setLoading(true))
         return UserService.getUser(id)
           .first()
           .flatMap { user in
               [
                 UserAction.setUser(user)
                 UserAction.setLoading(false)
               ].publisher
             }
           }
       }
     }
   }

   // Inside a view:

   func body(props: Props) -> some View {
     UserInfo(user: props.user)
       .onAppear { dispatch(UserAction.loadUser(byId: self.id)) }
   }
```.
