#secret_attr(name) ⇒ Object

Similar to .attr_accessor but with additional mechanisms to prevent exposing the internal value of the attribute

Examples:

class TheClass
  include Yast2::SecretAttributes

  attr_accessor :name
  secret_attr :password
end

one_object = TheClass.new
one_object.name = "Aa"
one_object.password = "42"

one_object.password # => "42"
one_object.inspect # => "#<TheClass:0x0f8 @password=<secret>, @name=\"Aa"\">"
