Overview

public

Defines the behavior for feature flag adapters.

Adapters are modules that are extended by Adapter. They must define three methods:

1. `fetch`: Returns persisted feature flag values for a given object.

2. `create`: Creates feature flags for a given object.

3. `update`: Updates feature flags for a given object.

4. `replace`: Replaces feature flags for a given object.

See Featuring::Persistence::ActiveRecord for a complete example.
