According to the docs, you call it this way:

rate = fedex.rate(:shipper=>shipper,
                  :recipient => recipient,
                  :packages => packages,
                  :service_type => "FEDEX_GROUND",
                  :shipping_options => shipping_options)

and then any of the instance variables (the @ variables) can be retrieved via an accessor:

puts rate.total_net_charge

It looks like the response is an array with one object of type Fedex::Rate. As mentioned by others, you should read the docs to see what Fedex::Rate exposes as methods. To programatically see the methods Fedex::Rate exposes you could use:

rate = response.first
puts rate.methods

Alternatively if you want to read the variables from the object (which is probably a bad idea), you could use:

rate.instance_variable_get('@total_freight_discounts')
