Errors related to schema versions
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
DownNotDefined
Fields
migration_index: usize
Index of the migration that caused the error
Migration has no down version
NoMigrationsDefined
Attempt to migrate when no migrations are defined
