OpenStruct allows you to create data objects and set arbitrary attributes. For example:
require 'ostruct' record = OpenStruct.new record.name = "John Smith" record.age = 70 record.pension = 300 puts record.name # -> "John Smith" puts record.address # -> nil
It is like a hash with a different way to access the data. In fact, it is implemented with a hash, and you can initialize it with one.
hash = { "country" => "Australia", :population => 20_000_000 }
data = OpenStruct.new(hash)
p data # -> <OpenStruct country="Australia" population=20000000>

Class Method Detail
new(hash=nil)
Create a new OpenStruct object. The optional hash, if given, will generate attributes and values. For example.
require 'ostruct'
hash = { "country" => "Australia", :population => 20_000_000 }
data = OpenStruct.new(hash)
p data # -> <OpenStruct country="Australia" population=20000000>
By default, the resulting OpenStruct object will have no attributes.
Instance Method Detail
==(other)
Compare this object and other for equality.
delete_field(name)
Remove the named field from the object.
initialize_copy(orig)
Duplicate an OpenStruct object members.
inspect()
Returns a string containing a detailed summary of the keys and values.
marshal_dump()
marshal_load(x)
new_ostruct_member(name)
to_s()
Alias for inspect
