def func 
   some code...
   rescue x,y,z
      do something...

I have a function where I'm trying to rescue an exception and then do something inside of rescue. I want to understand how to handle in case there is an exception again inside of the rescue block. This is a corner case and it is definitely necessary.

In case there is an exception again inside of rescue I want to be able to handle it. Any suggestions appreciated.

You can simply nest a rescue exception inside another rescue exception and you can do so using a number of different approaches depending on the situation but here are a couple:

begin

  do_something

rescue

  do_something_else rescue do_this_instead

end

OR

begin

  do_something

rescue

  begin
    do_something_else
  rescue
    do_this_instead
  end

end
