/// An outlet for the current content.

/// Only works as descendant of a [`Link`] component, otherwise it will be inactive.

/// The [`Outlet`] is aware of how many [`Outlet`]s it is nested within. It will render the content
/// of the active route that is __exactly as deep__.

/// - When the [`Outlet`] is not nested a [`Link`] component,
///   but only in debug builds.

/// # Example
/// ```rust
/// # use dioxus::prelude::*;
/// # use dioxus_router::prelude::*;
/// #[derive(Clone, Routable)]
/// #[rustfmt::skip]
/// enum Route {
///     #[nest("/wrap")]
///         #[layout(Wrapper)] // Every layout component must have one Outlet
///             #[route("/")]
///             Child {},
///         #[end_layout]
///     #[end_nest]
///     #[route("/")]
///     Index {},

/// #[component]
/// fn Index() -> Element {
