Sets

A set is a way to abstract away from a massive main function! Break up all of the big systems in your code, and register everything needed with a single function!

#[set]
fn SimpleSet(app: App) -> App {
   /// Do anything to the app here!
}

Super simple, and makes it even simpler to add it!

App::new(100).sets(SimpleSet)

You can add multiple sets in a single function, just like you can with widgets!

App::new(100).sets((SetOne, SetTwo))

And that's it!

Wait, why a capital case function?

That's because set's are actually structs that implement a trait! We do this in order to improve ergonomics, and allow for custom states! So when you write the #[set] above the function, you are actually telling the function to become a struct, and have the function body as a function tied to a trait!

What about states with data handling?

It's pretty simple! It's actually very similar to what you did above! Let's make a set that will register a function if and only if it's variable is set to true!

struct CustomSet {
   have_state: bool
}

impl Set for CustomSet {
   fn register_set(&self, app: App) -> App {
      if self.have_state {
         app.widget(...)
      } else {
         app
      }
   }
}

Wow! That's cool
