/// # Example
/// ```rust
/// # #[derive(Clone)]
/// # struct Logger;
/// use dioxus::prelude::*;
///
/// fn use_logger() -> Logger {
/// // We want one logger per app in the root. Instead of forcing the user to always provide a logger, we can insert a default logger if one doesn't exist.
/// use_root_context(|| Logger)
/// }
