This is weird, the tests worked fine locally. Perhaps something changed with the merge commit?

Manishearth · 2018-01-06T05:44:58Z

lol so it turns out if you write a crate using #[test], cargo test followed by cargo +otherrustc test will not recompile the tests even though the compiler changed.

Found the bug though.

Should work now, I forgot to add self.finger to index in the reverse iterator.
