/// Launch your Dioxus application with the given root component, context and config.
/// The platform will be determined from cargo features.
///
/// For a builder API, see `LaunchBuilder` defined in the `dioxus` crate.
///
/// # Feature selection
///
/// - `web`: Enables the web platform.
/// - `desktop`: Enables the desktop platform.
/// - `mobile`: Enables the mobile (ios + android webview) platform.
/// - `server`: Enables the server (axum + server-side-rendering) platform.
/// - `liveview`: Enables the liveview (websocke) platform.
/// - `native`: Enables the native (wgpu + winit renderer) platform.
///
/// Currently `native` is its own platform that is not compatible with desktop or mobile since it
/// unifies both platforms into one. If "desktop" and "native" are enabled, then the native renderer
/// will be used.
///
/// # Feature priority
///
/// If multiple renderers are enabled, the order of priority goes:
///
/// 1. liveview
/// 2. server
/// 3. native
/// 4. desktop
/// 5. mobile
/// 6. web
///
/// However, we don't recommend enabling multiple renderers at the same time due to feature conflicts
/// and bloating of the binary size.
///
/// # Example
/// ```rust, no_run
/// use dioxus::prelude::*;
///
/// fn main() {
///     dioxus::launch(app);
/// }
///
/// fn app() -> Element {
///     rsx! {
