README

        
Ensure that you have the furrylang toolchain installed.

Then invoke `cargo build --release` to build in ***release*** mode.

Then `./target/build/vlr-rs < /dev/urandom > /dev/null`, to make your CPU have hiccups.

## 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` doesn't have a `iter()` method.

  Second, `Range` 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`, is not implemented [(E0277)](https://doc.rust-lang.org/error-index.html#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.
