How do I use "each" on an Openstruct object?

I have a OpenStruct hash like this:

#<OpenStruct object1={
                       "param1"=>"2", 
                       "param2"=>"1"
                     }, 
             object2={
                       "param1"=>"2", 
                       "param2"=>"1"
                     }, 
             object3={
                       "param1"=>"2", 
                       "param2"=>"1"
                     }...

How can I use each on this?

OpenStruct has a method called marshal_dump that returns the underlying hash structure:

your_open_struct.marshal_dump.each{ |k,v| puts "#{k} => #{v}" }

If you are using Ruby 2.0, you can use also to_h like so:

your_open_struct.to_h.each{ |k,v| puts "#{k} => #{v}" }

Unlike marshal_dump, which returns the actual hash structure, to_h returns a hash with all the keys converted to symbols for easier access.
