Struct WhenOr 

pub struct WhenOr<Condition, Then, Or> { /* private fields */ }

A component that conditionally renders one of two views based on a reactive boolean condition.

The WhenOr component is created by calling the or method on a When component. It provides complete conditional rendering by rendering the “then” view when the condition is true, and the “or” view when the condition is false.

This component ensures that exactly one of the two views is always rendered, making it ideal for implementing UI states like loading/loaded, authenticated/unauthenticated, or any other binary state presentation.

Reactivity

The WhenOr component is fully reactive. When the condition changes, the UI will automatically switch between the two views without manual intervention.

Examples

use waterui::widget::condition::when;
use waterui_text::text;
use waterui_layout::stack::vstack;
use nami::binding;

let is_loading = binding(true);

when(!is_loading, || {
    vstack((
        "Welcome!",
        "Your data is ready.",
    ))
}).or(|| {
    vstack((
        "Loading...",
        // Could include a spinner component here
    ))
});
