Get non-clonable data from signals.

[humb1t]

I am writing a simple app, which as a main state uses non-clonable structure called Dizola. When I try to use it inside loosely coupled floem UI, I am facing issue that my brain fails to solve:

fn dictionary_view(dizola_state: RwSignal<Dizola<'static>>) -> AnyView {
    text(dizola_state.read_only().effect()).into_any() 
}

error[E0599]: no method named `effect` found for struct `ReadSignal` in the current scope
   --> src/gui.rs:111:35
    |
111 |     text(dizola_state.read_only().effect()).into_any()
    |                                   ^^^^^^ method not found in `ReadSignal<Dizola<'_>>`

When I try to use text(dizola_state.get().effect()).into_any() get on RwSignal I see the error:

error[E0599]: the method `get` exists for struct `floem::prelude::RwSignal<Dizola<'static>>`, but its trait bounds were not satisfied
   --> src/gui.rs:111:23
    |
111 |     text(dizola_state.get().effect()).into_any()

and it is because method implemented only for signals, which store type that is clonable. I am new to floem and it's reactive system, and because of that I can't understand why clone is needed in this situation? If someone can give me some hints on that matter, or share good examples on how to work with floem (without clone and without putting signals inside your state structure), I will really appreciate that.

.get() needs the data stored is Clone. The one you need in this case is .with()

Thanks a lot @dzhou121 - worked like a charm!
