Scope

Scope stores a View factory as an independent recomposition boundary. Most application code should use [[huxerui::scope]], which generates this boundary automatically while preserving natural function syntax.

Prefer generated scope syntax

[[huxerui::scope]]
View Counter() {
  auto count = UseState(0);
  return Column {
    Text::Format("Count: {}", count),
    Button("Increment").OnClick([count] {
      count += 1;
    }),
  }.With(Spacing(12.0F));
}

Bind an existing factory

Explicit construction is useful when a factory is already available as a value:

Scope(content_factory)

The variadic constructor binds a compatible factory and copyable arguments without requiring an application-authored forwarding lambda:

Scope(ProfilePage, user_id)

Own scoped lifetime

State, event hubs, task scopes, and lifecycle registrations belong to the scope that creates them. Do not add scopes to every helper function; stateless composition should stay an ordinary function returning View.

Scope adds no semantic role of its own; its returned child supplies the semantic subtree.

API

• Scope(std::function<View()> factory).
• Scope(Factory&& factory, Arguments&&... arguments) for a compatible view factory.
• Preferred declaration syntax: [[huxerui::scope]] View Component(...).

Read Composition and identity before introducing explicit scope boundaries or keys.
