Linq-in-Rust VS pariter

Rust has rather sophisticated macros, which let you do stuff like this outside the core language implementation, which is IMO very much where such things belong.

E.g. a linq clone in rust can look like this: https://github.com/StardustDL/Linq-in-Rust

    linq!(from p in 1..100, where p <= &5, orderby -p, select p * 2).collect();

Once you have something working, and you want to make it fast, run cargo install flamegraph, and then cargo flamegraph, to see where your code is spending its time. Once you've fixed any hot spots that you weren't expecting, you can try using rayon or https://github.com/dpc/pariter to start making use of more CPU cores.

Parallel iterators: rayon or what I ended up using because I wanted to keep the original order is this amazing library: https://github.com/dpc/pariter

There is also https://github.com/dpc/pariter which is similar to rayon but preserves order of tasks.

All right, I've got it working. https://github.com/dpc/pariter/tree/non-static-f
