Consuming a ParallelIterator with a for loop

[kpcyrd]

It seems all rayon examples use something functional like .sum() or for_each with a function that can be executed in parallel.

Sometimes I want to run a .map() in parallel for each item but consume the results sequentially with a for loop. Is there a way to do that?

I'm currently back to rolling my own with the threadpool crate.

We don't have this in rayon yet -- #210.

In the meantime, you might like the par-map crate as an alternative.

Closing as a duplicate of #210 --thanks @kpcyrd !

Here is my solution: #1071
