How Metal is different than Rack?

I just watched Railscasts #150 Rails Metal and I got a question to ask.

How Metal is different than Rack? Is Metal just Rails effort to be Rack compatible? And when to use what?

Thanks in advance!

UPDATE:

Here is I found a good answer on my question.

What is the exact difference between Rack and Rails Metal in Ruby on Rails

Metal is / was supposed to be a subset of Rack. It had the same rack interface for compatibility purposes.
I think Rails was reverted back to use rack in version 3, so you won't find much about metal anymore.
