   Hope we could get a little performance improvement from it because faster arithmetical calculation is used:
   ```rust
   pub fn round_upto_power_of_2(num: usize, factor: usize) -> usize {
       debug_assert!(factor > 0 && (factor & (factor - 1)) == 0);
       (num + (factor - 1)) & !(factor - 1)
   }
   ```
