torrentSize :: Torrent -> Integer #

Size of the files in the torrent.

showTorrent :: Torrent -> ByteString #

generates a torrent file

Due to lexographical ordering requirements of BEncoded data, this should generate the same ByteString that readTorrent read to generate the Torrent. However, torrent files may contain extensions and nonstandard fields that prevent that from holding for all torrent files.
