Parallel execution

[thibran]

It would be nice if loop-rs could run the loop body in parallel (using num-cpu).
Suggestion for the flag name: --parallel -p.

I think I'd be fine with this, although it introduces some questions - what happens to $COUNT, etc.

I'd be happy with this if it could be implemented in a simple way with strong bounds on the requirements that don't creep into a huge mess. At a certain point, just use parallel rather than loop.

Want to try a PR?

First thought was: well this will be a lot of work and I shouldn't start yet another project, but then looking at the code I think I can give it a try 😃

Do you have a reason not to use the Rust 2018 edition?

One of the goals for the year is to have this included in Debian, which means targeting specific version. However, I don't have specific information that would prevent us using newer Rust.
