SQLite Transactor

Describes a function which is provided as a transactional closure to the SQLite driver; the transactor executes the steps of the transaction itself, and may be subject to rollback or retries as determined by the engine.

This type is typically not accessible directly by user code, but is instead consumed by the SQLiteTransaction created by the driver to facilitate execution.

 

Idempotency

Because transactions are subject to rollback and retry, the transactor should be idempotent; that is, it should be safe to execute the transaction multiple times without causing side effects.

For more information about transaction behavior, see the SQLiteTransaction documentation.

Parameters

R

Return value type.
