Function single_executor::spawn_blocking

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

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