internal/versioned_schema library
Defines base classes to generate lightweight tables and views. This library
is used by code generated via drift_dev schema steps to generate snapshots
of every schema version of your database without much overhead.
For more information on how to use that feature, see https://drift.simonbinder.eu/docs/advanced-features/migrations/#step-by-step
Warning: This library is not meant to be imported into user-written code, and classes defined in this library are not part of drift's stable API.
