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

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

Example

require 'json/add/ostruct'
x = OpenStruct.new('name' => 'Rowdy', :age => nil).as_json
# => {"json_class"=>"OpenStruct", "t"=>{:name=>'Rowdy', :age=>nil}}

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

Example

OpenStruct.json_create(x)
# => #<OpenStruct name='Rowdy', age=nil>
