NamedStruct 
Simple object to wrap your configuration, it can be instantiated only with required named arguments.
Usually you do :
class MyConfig
att_reader :a, :b, :c
def initialize(a:, b:, c:)
@a = a
@b = b
@c = c
end
end
But now you can :
class MyConfig < NamedStruct::Config
attr_required :a, :b, :c
end
Installation
Add this line to your application's Gemfile:
gem 'named_struct'
And then execute:
$ bundle
Or install it yourself as:
$ gem install named_struct
Usage
require 'named_struct'
class MyConfig < NamedStruct::Config
attr_required :a, :b, :c
end
my_config = MyConfig.new(a: 10, b: 20, c: 30)
class MySuperAlgorithm
def initialize(my_param, **config)
@my_param = my_param
@config = MyConfig.new(**config)
end
end
MySuperAlgirithm.new("some param", a: 12, b: 10, c: 50)
