pub fn try_spawn_blocking<F, T, CS>(
    function: F
) -> Result<(impl Future<Output = T> + 'static + Send, CS::ThreadHandle), CS::SpawnError> where
    F: FnOnce() -> T + Send + 'static,
    T: 'static + Send,
    CS: TryThreadSpawner<()>, 

Returns a future that will contain the result of function. Function will be called in another thread as to not block the main thread. Fallible version of spawn_blocking.
