How to trigger binding action intentionally?

[Jager-yoo]

Let's suppose that we have two @BindableState 'userID' and 'userEmail' with initialValues.
Those are connected to TextFields and the Reducer has:

case .binding(\.$userID):
  /* some local validations... */
  enum RequestUserNameID { }
  return env.checkUserName(state) // validates with server
    .map(Action.fetchCheckUserID)
    .cancellable(id: RequestUserNameID.self, cancelInFlight: true)

case .binding(\.$userEmail):
  /* some local validations... */
  enum RequestUserEmailID { }
  return env.checkUserEmail(state) // validates with server
    .map(Action.fetchCheckUserEmail)
    .cancellable(id: RequestUserEmailID.self, cancelInFlight: true)

I just want to trigger these binding actions intentionally, without modifying TextFields.
I tried Effect(value:) from another action case, but I'm not sure what to put as a binding argument. 🤷🏻

Any ideas will be very appreciated. Thanks!

Hey @Jager-yoo! It would be .binding(.set(\.$userEmail, "something")), but you can maybe also refactor your domain to produce the same effect than the one from case .binding(\.$userEmail) using private functions. Re-emitting actions to reuse code is indeed inefficient, as you can read in the "Performance" article.

Hey! @tgrapperon, thank you so much!
The way you told me solved the problem I'm dealing with.
Also thanks for the performance article reference, really need to separate shared actions...
