programming help

werking on software bug for mt work (cant say what).

the file keeps corupting when i send it 2 my coworkers. it can read from stdin but shows no testing error.  ive put hear is the use of Box for type-erasure so io::stdin can be susbituted for the fs::File handle. the odd construct &* extracks the character sequence hidden inside the (Option-wrapped) String produced by nth() is functioning but still is not werking. not an email ishue :/
