Methods Struct#as_json
and Struct.json_create
may be used to serialize and deserialize a Struct object; see Marshal.
Method Struct#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>
# File json/lib/json/add/struct.rb, line 30 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
