power_struct

PowerStruct

Simple Struct replacement with mandatory keyword arguments.

Reasons to use PowerStruct:

• Argument order no longer matters
• Initialization arguments are mandatory by default
• Cheesy name

Installation

Add this line to your application's Gemfile:

gem 'power_struct'

And then execute:

$ bundle

Or install it yourself as:

$ gem install power_struct

Usage

require "power_struct"

MyStruct = PowerStruct.new(:attr1, attr2: :attr2_default)

my_struct = MyStruct.new(attr1: "attr1_value")
my_struct.attr1 # => "attr1_value"
my_struct.attr2 # => :attr2_default
my_struct.attr2 = 1
my_struct.attr2 # => 1

my_struct = MyStruct.new # => raises exception, attr1 is mandatory
