    #as_json  
  



  

    

Methods as_json and .json_create may be used to serialize and deserialize a Struct object; see Marshal.



Method as_json serializes self, returning a 2-element hash representing self:



require 'json/add/struct'
Customer = Struct.new('Customer', :name, :address, :zip)
x = Struct::Customer.new.as_json
# => {"json_class"=>"Struct::Customer", "v"=>[nil, nil, nil]}



Method JSON.create deserializes such a hash, returning a Struct object:



Struct::Customer.json_create(x)
# => #<struct Struct::Customer name=nil, address=nil, zip=nil>

def as_json(*)
  klass = self.class.name
  klass.to_s.empty? and raise JSON::JSONError, "Only named structs are supported!"
  {
    JSON.create_id => klass,
    'v'            => values,
  }
end


  








  

    #to_json(*args)  
  



  

    

Returns a ::JSON string representing self:



require 'json/add/struct'
Customer = Struct.new('Customer', :name, :address, :zip)
puts Struct::Customer.new.to_json



Output:



{"json_class":"Struct","t":{'name':'Rowdy',"age":null}}
