Struct Transaction 

pub struct Transaction<'conn> { /* private fields */ }

An open database transaction.

Created via Connection::transaction or Connection::transaction_immediate. If the Transaction is dropped without calling commit, the transaction is rolled back automatically.

Implementations

impl<'conn> Transaction<'conn>

pub fn commit(self) -> DbResult<()>

Commits the transaction.

Errors

Returns Error if the COMMIT statement fails.

pub fn execute_batch(&self, sql: &str) -> DbResult<()>

See Connection::execute_batch.

Errors

Returns Error if any statement fails.

pub fn execute(&self, sql: &str, params: &[Value]) -> DbResult<usize>

See Connection::execute.

Errors

Returns Error if preparation or execution fails.

pub fn query_row<T>( &self, sql: &str, params: &[Value], mapper: impl FnOnce(&Row<'_, '_>) -> DbResult<T>, ) -> DbResult<T>

See Connection::query_row.

Errors

Returns Error if preparation, execution, or the mapper fails.

pub fn prepare(&self, sql: &str) -> DbResult<Statement<'_>>

See Connection::prepare.

Errors

Returns Error if the SQL is invalid.

Trait Implementations

impl Drop for Transaction<'_>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
