Bytesrw_xxhash.Xxh64.{to_hex,pp}. Leading zeros were not being printed (#5).Slice.break: do not return None if any of Slice.take or Slice.drop does. Simply return the result of both operations.Slice.{sub,make}[_or_eod]. The functions now behave like Bytes.sub as far as indexing is allowed. Thanks to Adrián Montesinos González for the report and suggesting the fix (#4).bytesrw.* libraries are made to export bytesrw.
