}
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.
DuplicateKeyUpdate(Vec<Assignment>)
ON DUPLICATE KEY UPDATE (MySQL when the key already exists, then execute an update instead)
OnConflict(OnConflict)
ON CONFLICT is a PostgreSQL and Sqlite extension
