Module barrel::migration

Core migration creation handler

A migration can be done for a specific schema which contains multiple additions or removables from a database or table.

At the end of crafting a migration you can use Migration::exec to get the raw SQL string for a database backend or Migration::revert to try to auto-infer the migration rollback. In cases where that can't be done the Result<String, RevertError> will not unwrap.

You can also use Migration::exec with your SQL connection for convenience if you're a library developer.
