error[E0277]: the trait bound `u64: From<usize>` is not satisfied

    = help: the following implementations were found:
              <u64 as From<&'a rend::BigEndian<u64>>>
              <u64 as From<&'a rend::LittleEndian<u64>>>
              <u64 as From<&'a rend::NativeEndian<u64>>>
              <u64 as From<NonZeroU64>>
            and 8 others
    = note: required because of the requirements on the impl of `Into<u64>` for `usize`
