All contributions to Dossier must come well-tested.
Dossier currently has Dossier::Adapter::ActiveRecord, which allows it to get an ActiveRecord connection and use it for escaping queries, and executing them. It wraps the returned result object in a Dossier::Adapter::ActiveRecord::Result, which simply provides a standard way of getting headers and rows.
If you'd like to add the ability to use a different ORM's connections, you'd need to add a new adapter class and a new adapter result class.
You'd also need to update Client#loaded_orms to check for the presence of your ORM.
