@state (and @input) is an instance of Camping::H. Camping::H is a Hash with
some sugar. You can use it like a regular Hash (it's actually a subclass of
Hash):
@state["user_id"] = 1
@state["user_id"] # => 1
But it also supports method-like access:
@state.user_id = 1
@state.user_id # => 1
As long as it's not a method on Hash, you can use it as a getter/setter.
You can save anything that can be serialized using Marshal:
Marshal.dump(123) # => "\x04\bi\x01{"
Marshal.load("\x04\bi\x01{") # => 123
