View Source Backpex.Adapter behaviour (Backpex v0.8.2)

Specification of the datalayer adapter.

Work in progress

The Backpex.Adapter behaviour is currently under heavy development and will change drastically in future updates. Backpex started out as Ecto-only and this is still deeply embedded in the core. We are working on changing this. Do not rely on the current API to build new adapters, as the callbacks will still change significantly. This will be an iterative process over the next few releases.
