Just maybe investigate if using another way to write for example take_while without bounds checks. It could be worth it if it helps performance.

See this issue for reference: rust-lang/rust/issues/30112

In particular this comment shows the kind of find-then-split loop that optimizes out the bounds check in the compiler today: rust-lang/rust#30112 (comment)
