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.
InvalidSavepoint
This savepoint is invalid or cannot be created.
Savepoints become invalid when an older savepoint is restored after it was created, and savepoints cannot be created if the transaction is “dirty” (any tables have been opened)
Storage(StorageError)
Error from underlying storage
