There was a problem hiding this comment.
This looks okay to me.
@bors r+ rollup
With regards to your #[inline] question, I assume not. It looks like some of the into_array methods are already #[inline], while others are not.

…cked, r=Darksonn Eliminate double length check in `Vec::into_array` Linked issue: rust-lang#148082 As an aside, has the question of whether `Vec::into_boxed_slice` and `RawVec::into_box` should be `#[inline]` been considered? That might allow length information to be retained and used for optimization.
