pub enum MigrationConflictStrategy {
Drop,
Raise,
BackupAndDrop,
}
Expand description
Sometimes Migrations can’t proceed without having to drop existing data. This allows you to configure, how these cases should be handled.
Variants§
Drop
Just drop the data, we don’t care that we have to sync again
Raise
Raise a IndexeddbStateStoreError::MigrationConflict
error with the
path to the DB in question. The caller then has to take care about
what they want to do and try again after.
BackupAndDrop
Default.
