//! Error boundary component for graceful error handling

use leptos::prelude::*;

/// Error fallback component
///
/// Displays user-friendly error messages with retry functionality.
/// Use within Suspense error handling or as standalone error display.

/// # Example
/// ```ignore

///     <ErrorFallback
///         error="Failed to load data".to_string()
///         on_retry=Callback::new(move |_| window().location().reload().unwrap())
///     />
/// }
/// ```

/// Simple error boundary wrapper using Show
///
/// Use Show component directly in your views for conditional error display.
/// This is a convenience re-export to make the pattern more discoverable.

/// # Example
/// ```ignore
/// let (error, set_error) = signal(None::<String>);
///
/// view! {
///     <Show
///         when=move || error.get().is_none()
///         fallback=move || {
///             view! {
///                 <ErrorFallback
///                     error=error.get().unwrap_or_default()
///                     on_retry=Callback::new(move |_| set_error.set(None))

///         }
///     >
///         <MyComponent />
