[jessegrosjean]

However I understand that Rayon only works on an arraylike type (ie. it cant work on an iterator)

It actually can work on iterators using par_bridge. Here's an example of doing that:

Sanity check: Code to concurrently process items from iterator in rayon

Wow, that's awesome and does exactly what I want. Thanks! And it was all right there in the docs, even with channels as example use case . I hadn't come across the try pattern for iterators yet and so those methods didn't stand out to me. And after not being able to do what I wanted with the default map I got side tracked trying to work with rayon at a lower level. For anyone following along here's a much shorter way to do what I was trying to do in original post: pub fn process_it…
