    * - If all operations successfully complete and the `commitTransaction` operation is successful, then the provided function will return the result of the provided function.
    * - If the transaction is unable to complete or an error is thrown from within the provided function, then the provided function will throw an error.
    *   - If the transaction is manually aborted within the provided function it will not throw.
    * - If the driver needs to attempt to retry the operations, the provided function may be called multiple times.
