The man page for ets:slot/2 explains how the function works:

   This  function  is  mostly  for debugging purposes, Normally one
   should use first/next or last/prev instead.

   Returns all objects in the I:th slot of the table Tab.  A  table
   can  be  traversed  by repeatedly calling the function, starting
   with the first slot  I=0  and  ending  when  '$end_of_table'  is
   returned.  The  function  will  fail with reason badarg if the I
   argument is out of range.
