The values in the vector are of type &str. But within the tests, the additional & is changing the test strings to type &&str resulting in error E0308 (mismatched types).
error[E0308]: mismatched types

| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected `str`, found `&str`

= note: expected enum `Option<&str>`
found enum `Option<&&str>`
= note: this error originates in the macro `assert_eq` (in Nightly builds, run with -Z macro-backtrace for more info)
(I sure hope that comes out formatted correctly.)
