DataMigration

Type safe data migrations.

All you need to do is create a type family to index your record and provide an instance of Transform to migrate your data between versions.

Migrations are type-safe and the library uses generics to remove as much boiler-plate as possible.

Future Considerations

In the future this library will provide a high-level DSL to enable better ergonomics around type errors so that you can see which fields require specification in the migration.
