error[E0277]: the trait bound `i32: From<u32>` is not satisfied

    |
    = help: the following implementations were found:
              <i32 as From<NonZeroI32>>
              <i32 as From<bool>>
              <i32 as From<i16>>
              <i32 as From<i8>>
            and 3 others
    = note: required because of the requirements on the impl of `Into<i32>` for `u32`
