FAQ

• Why are you using (0..8).into_par_iter() instead of (0..8), (0..8).into_iter(), (0..8).iter()? Isn't that "abusing" parallelism?

  First, Range<T> doesn't have a iter() method.
  Second, Range<T> is an iterator already so into_iter() is redundant here.
  Third, ParallelIterator::flat_map() requires a closure that returns a type satisfying IntoParallelIterator trait
  which, for Map<T>, is not implemented (E0277). Thus we must use
  .into_par_iter() in order to comply trait bounds.

  So even if it's labelled as "abuse", this is what the API forces.

• Why are you collect()ing? Can't you use collect_to_vec() or .enumerate().for_each() and collect to a custom buffer?

  First, to be a little bit fair to the C code. Second, no I can't because IntoIndexedParallelIterator is not implemented for
  FlatMap nor there is a way to turn it so.

This work is composed by means of attacking the Rust programming language community to point out their
amateurness in the field of parallel computing. I beg of you rustaceans, to stop conducting these actions
and pollute the field of computer science. Thank you.
