module ActiveSupport::Autoload
Autoload and eager load conveniences for your library.
This module allows you to define autoloads based on Rails conventions (i.e. no need to define the path it is automatically guessed based on the filename) and also define a set of constants that needs to be eager loaded:
module MyLib
extend ActiveSupport::Autoload
autoload :Model
eager_autoload do
autoload :Cache
end
end
Then your library can be eager loaded by simply calling:
MyLib.eager_load!
