Struct Transaction 

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

A transaction on a Connection connection.

Dropping a transaction before commit or rollback follows the behavior of the selected driver.

While the transaction is alive, it keeps the Connection borrowed.

Implementations

impl Transaction<'_>

pub fn driver(&self) -> Driver

Returns the selected driver.

pub async fn query(&mut self, sql: &str) -> Result<Rows<'_>>

Runs SQL inside the transaction.

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

Prepares SQL inside the transaction.

pub async fn commit(self) -> Result<()>

Commits the transaction.

pub async fn rollback(self) -> Result<()>

Rolls the transaction back.

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.

impl Executor for &mut Transaction<'_>

type Rows<'a> = Rows<'a> where Self: 'a

Row stream returned by this executor.

type Statement<'a> = Statement<'a> where Self: 'a

Prepared statement returned by this executor.

fn driver(&self) -> Driver

Returns the selected database driver.

async fn query(&mut self, sql: &str) -> Result<Self::Rows<'_>>

Runs SQL without explicit bound parameters.

async fn query_prepared_source<P>( &mut self, sql: &str, params: &P, ) -> Result<Self::Rows<'_>>

where P: ParamSource + ?Sized,

Runs SQL with a borrowed parameter source.

async fn prepare(&mut self, sql: &str) -> Result<Self::Statement<'_>>

Prepares SQL for repeated use.

impl Executor for Transaction<'_>

type Rows<'a> = Rows<'a> where Self: 'a
