These adaptors consume may many elements before deferring to a base folder's fullness checks, and so they need to be performed manually. For the `filter`s, there's no way to do it manually (rayon-rs#632), so the specialisations just have to be removed. For `fold` and `find_any` this can be done with a `take_while`. This extends the octillion tests to confirm this behaviour. This makes a program like the following slightly slower compared to the direct `consume_iter` without a check, but it's still faster than the non-specialized form. ``` extern crate test; extern crate rayon; use rayon::prelude::*; fn main() { let count = (0..std::u32::MAX) .into_par_iter() .map(test::black_box) .find_any(|_| test::black_box(false)); println!("{:?}", count); } ``` ``` $ hyperfine ./find-original ./find-no-check ./find-check Benchmark rayon-rs#1: ./find-original Time (mean ± σ): 627.6 ms ± 25.7 ms [User: 7.130 s, System: 0.014 s] Range (min … max): 588.4 ms … 656.4 ms 10 runs Benchmark rayon-rs#2: ./find-no-check Time (mean ± σ): 481.5 ms ± 10.8 ms [User: 5.415 s, System: 0.013 s] Range (min … max): 468.9 ms … 498.2 ms 10 runs Benchmark rayon-rs#3: ./find-check Time (mean ± σ): 562.3 ms ± 11.8 ms [User: 6.363 s, System: 0.013 s] Range (min … max): 542.5 ms … 578.2 ms 10 runs ``` (find-original = without specialization, find-no-check = custom `consume_iter` without `take_while`, find-check = this commit)
