…rom_slice` (#9332) `Vec::extend_from_slice` may be more efficient than `Vec::extend`. I'm not 100% sure of that - specialization may make the two equivalent where the iterator passed to `Vec::extend` is a slice iterator. But anyway `extend_from_slice` is intended for this use case, so better to use it.
