Readers
By default public attribute reader is defined for every param and option.
You can define private or protected reader instead:
require 'dry-initializer'
class User
extend Dry::Initializer
param :name, reader: :private # the same as adding `private :name`
param :email, reader: :protected # the same as adding `protected :email`
end
To skip any reader, use reader: false:
require 'dry-initializer'
class User
extend Dry::Initializer
param :name
param :email, reader: false
end
user = User.new 'Luke', 'luke@example.com'
user.name # => 'Luke'
user.email # => #<NoMethodError ...>
user.instance_variable_get :@email # => 'luke@example.com'
Notice that any other value except for false, :protected and :private provides a public reader.
No writers are defined. Define them using pure ruby attr_writer when necessary.
