Ash.Resource.Change behaviour (ash v1.37.2) View Source

The behaviour for an action-specific resource change.

To implement one, simply implement the behaviour. init/1 is defined automatically by use Ash.Resource.Change, but can be implemented if you want to validate/transform any options passed to the module.

The main function is change/3. It takes the changeset, any options that were provided when this change was configured on a resource, and the context, which currently only has the actor.
