Raising an exception within AMQP about amqp

[botanicus]

Sriram, this is not a mailing list or IRC, please next time ask there. You can use exceptions as long as you don't have any async code in begin/rescue block. For async code, there should be an option to handle exceptions via callback. I'm not so familiar with EventMachine, but i. e. in Node.js you have code like:

fs.unlink('/tmp/hello', function (err) {
  if (err) throw err;
  console.log('successfully deleted /tmp/hello');
});

So you'll simply get an exception instance to the callback so you can handle it (so it's passed as an argument, not raised!). In EventMachine, I believe, defferable objects has #errback method, so you can do mydef.callback { # what'll happen on success } and mydef.errback { |error| # what'll happen on error }. But I don't remember exactly, check the documentation.
