3/// The aggregate form state.
4///
5/// Constructed once per `<form>` via `App::use_form()`,
6/// threaded through the form's inputs and the submit
7/// handler. Cheap to `Clone` (the four internal signals are
8/// each `Copy`-by-pointer).
9///
10/// # Field reactivity
11///
12/// `values`, `errors`, `touched`, and `submitting` are all
13/// `Signal`s, so any `html!` body that calls
14/// `state.values().get()` (or any of the other three) inside
15/// its render closure re-renders when the corresponding
16/// signal changes. There is no manual subscribe API; the
17/// reactive read IS the subscription.
