As Layout::array's document said, when the total size would exceed isize::MAX, returns LayoutError. Not the usize::MAX.

nomicon/src/vec/vec-alloc.md

Lines 178 to 182 in 0d5f884

// `Layout::array` checks that the number of bytes is <= usize::MAX,
// but this is redundant since old_layout.size() <= isize::MAX,
// so the `unwrap` should never fail.
let new_layout = Layout::array::<T>(new_cap).unwrap();
(new_cap, new_layout)
