The easiest way is to create a MyStruct and add "--- !ruby/ 
struct:MyStruct" to your YAML then use YAML.load.  This way you can  
round-trip without pain.

$ ruby
require 'yaml'

MyStruct = Struct.new :key_1, :key_2

data = MyStruct.new 'Value 1', 'Value 2'

yaml = data.to_yaml

puts yaml

newdata = YAML.load yaml

p newdata
--- !ruby/struct:MyStruct
key_1: Value 1
key_2: Value 2
#<struct MyStruct key_1="Value 1", key_2="Value 2">
