rust

00000000  41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41  |AAAAAAAAAAAAAAAA|
00000010  41 41 41 41 41 42 72 54 59 74 79 52 54 72 54 74  |AAAAABrTYtyRTrTt|
00000020  59 47 63                                         |YGc|

only on console the error appears on

that is improper error handling, errors are only only in console but the output it not displayed any error
