Code before:
    #[track_caller]
    pub fn current() -> Self {
        Handle {
            inner: scheduler::Handle::current(),
        }
    }

    /// Returns a Handle view over the currently running Runtime
    ///
    /// Returns an error if no Runtime has been started
    ///
    /// Contrary to `current`, this never panics
    pub fn try_current() -> Result<Self, TryCurrentError> {
        context::with_current(|inner| Handle {
            inner: inner.clone(),
        })
    }

    /// Spawns a future onto the Tokio runtime.
    ///
    /// This spawns the given future onto the runtime's executor, usually a
    /// thread pool. The thread pool is then responsible for polling the future
    /// until it completes.
    ///
    /// Executes the given future. Depending on the current [`Runtime`](crate::runtime::Runtime),
    /// it may start immediately in the background or require blocking on the [`JoinHandle`].
    ///
