.for_each() on a future of Vec<T>

help
1

Hello there,

is there a way to either convert a Future<Item=Vec<T>, Error=E> into a Stream or to run a for_each() command on a future of a Vec<T> ?

I'm trying to write something more elegant than

futures::future::ok(vec![1,2,3])
    .map(|vec| {
        vec.iter().for_each(some_fn);
        Ok(())
    })

Thanks in advance :slight_smile:

If it's a vec of regular items, not a vec of futures, then mixing it with the future-spawning machinery is entirely unnecessary.

Your code seems fine. If you use this pattern a lot, you can make your own trait with a helper method.

No it's actually deep within a chain of futures that one future is returning a Vec<T>. I started by chaining with a for_each() and was surprised to see the compiler returning an error :slight_smile:
