I just noticed that the documentation on Vec::spare_capacity_mut(&mut self) -> &mut [MaybeUninit<T>] has a hover icon with "Notable traits for &'_ [u8]". MaybeUninit<T> can never be a u8 (though it could be MaybeUninit<u8>), so this information is irrelevant.

I saw that on documentation for "Version 1.48.0-nightly (a1947b3 2020-09-10)".
