-# = ostruct.rb: OpenStruct implementation

-#

-# Author:: Yukihiro Matsumoto

-# Documentation:: Gavin Sinclair

-#

-# OpenStruct allows the creation of data objects with arbitrary attributes.

-# See OpenStruct for an example.

-#

-

-#

-# An OpenStruct is a data structure, similar to a Hash, that allows the

-# definition of arbitrary attributes with their accompanying values. This is

-# accomplished by using Ruby's metaprogramming to define methods on the class

-# itself.

-#

-# == Examples

-#

-# require "ostruct"

-#

-# person = OpenStruct.new

-# person.name = "John Smith"

-# person.age = 70

-#

-# person.name # => "John Smith"

-# person.age # => 70

-# person.address # => nil

-#

-# An OpenStruct employs a Hash internally to store the attributes and values

-# and can even be initialized with one:

-#

-# australia = OpenStruct.new(:country => "Australia", :capital => "Canberra")

-# # => #<OpenStruct country="Australia", capital="Canberra">

-#

-# Hash keys with spaces or characters that could normally not be used for

-# method calls (e.g. <code>()[]*</code>) will not be immediately available

-# on the OpenStruct object as a method for retrieval or assignment, but can

-# still be reached through the Object#send method or using [].

-#

-# measurements = OpenStruct.new("length (in inches)" => 24)

-# measurements[:"length (in inches)"] # => 24

-# measurements.send("length (in inches)") # => 24

-#

-# message = OpenStruct.new(:queued? => true)

-# message.queued? # => true

-# message.send("queued?=", false)

-# message.queued? # => false

-#

-# Removing the presence of an attribute requires the execution of the

-# delete_field method as setting the property value to +nil+ will not

-# remove the attribute.

-#

-# first_pet = OpenStruct.new(:name => "Rowdy", :owner => "John Smith")

-# second_pet = OpenStruct.new(:name => "Rowdy")

-#

-# first_pet.owner = nil

-# first_pet # => #<OpenStruct name="Rowdy", owner=nil>

-# first_pet == second_pet # => false

-#

-# first_pet.delete_field(:owner)

-# first_pet # => #<OpenStruct name="Rowdy">

-# first_pet == second_pet # => true

-#

-# Ractor compatibility: A frozen OpenStruct with shareable values is itself shareable.

-#

-# == Caveats

-#

-# An OpenStruct utilizes Ruby's method lookup structure to find and define the

-# necessary methods for properties. This is accomplished through the methods

-# method_missing and define_singleton_method.

-#

-# This should be a consideration if there is a concern about the performance of

-# the objects that are created, as there is much more overhead in the setting

-# of these properties compared to using a Hash or a Struct.

-# Creating an open struct from a small Hash and accessing a few of the

-# entries can be 200 times slower than accessing the hash directly.

-#

-# This is a potential security issue; building OpenStruct from untrusted user data

-# (e.g. JSON web request) may be susceptible to a "symbol denial of service" attack

-# since the keys create methods and names of methods are never garbage collected.

-#

-# This may also be the source of incompatibilities between Ruby versions:

-#

-# o = OpenStruct.new

-# o.then # => nil in Ruby < 2.6, enumerator for Ruby >= 2.6

-#

-# Builtin methods may be overwritten this way, which may be a source of bugs

-# or security issues:

-#

-# o = OpenStruct.new

-# o.methods # => [:to_h, :marshal_load, :marshal_dump, :each_pair, ...

-# o.methods = [:foo, :bar]

-# o.methods # => [:foo, :bar]

-#

-# To help remedy clashes, OpenStruct uses only protected/private methods ending with <code>!</code>

-# and defines aliases for builtin public methods by adding a <code>!</code>:

-#

-# o = OpenStruct.new(make: 'Bentley', class: :luxury)

-# o.class # => :luxury

-# o.class! # => OpenStruct

-#

-# It is recommended (but not enforced) to not use fields ending in <code>!</code>;

-# Note that a subclass' methods may not be overwritten, nor can OpenStruct's own methods

-# ending with <code>!</code>.

-#

-# For all these reasons, consider not using OpenStruct at all.
