/// Create a new error boundary component.

/// ## Details
///
/// Error boundaries handle errors within a specific part of your application. Any errors passed in a child with [`Throw`] will be caught by the nearest error boundary.
///
/// ## Example
///
/// ```rust, ignore
/// rsx!{
/// ErrorBoundary {
/// handle_error: |error| rsx! { "Oops, we encountered an error. Please report {error} to the developer of this application" }
/// ThrowsError {}
/// }
/// }
/// ```
///
/// ## Usage
///
/// Error boundaries are an easy way to handle errors in your application.
/// They are similar to `try/catch` in JavaScript, but they only catch errors in the tree below them.
/// Error boundaries are quick to implement, but it can be useful to individually handle errors in your components to provide a better user experience when you know that an error is likely to occur.
