I looked into this a bit, and apparently there are not tests for the Rust rewrite. That's because it does not compile at all -- not even on Rust 1.36!

@anp, could you clarify what benchmarks you are referring to with this issue?

EDIT: It seems there is test code, it is just not in #[test] blocks. However, the inability to compile is still a problem. Are they still useful?

The compiler error, for the record:

Alas! Thanks for looking into it. IIRC, this was originally referring to https://medium.com/@robertgrosse/parallelizing-enjarify-in-go-and-rust-21055d64af7e and some related posts about comparing the rewrites.
