Function promising_future::all

pub fn all<T, I, F>(futures: I) -> Future<F> where
    T: Send + 'static,
    I: IntoIterator<Item = Future<T>> + Send + 'static,
    F: FromIterator<T> + Send + 'static, 

Return a Future of all values in an iterator of Futures.

Take an iterator producing Future<T> values and return a Future<Vec<T>>.

This function is non-blocking; the blocking occurs within a thread. This uses std::thread::spawn() to create the thread needed to block.
