     - Vec::truncate()
     - Vec::resize()
     - Vec::clear()
     - Vec::pop()
     - Vec::push_within_capacity()
       - new error type: PushError
     - Vec::drain_all()
     - Vec::retain()
     - Vec::remove()
       - new error type: RemoveError
     - Vec::insert_within_capacity
       - new error type: InsertError
   - simplify Vec::push() using Vec::spare_capacity_mut()
   - split Vec::set_len() into Vec::inc_len() and Vec::dec_len()
     - add type invariant Vec::len() <= Vec::capacity
     - simplify Vec::truncate() using Vec::dec_len()
