Struct Transaction 

pub struct Transaction { /* private fields */ }

An open transaction, holding its connection until it ends.

Implementations

impl Transaction

pub fn dialect(&self) -> &dyn Dialect

The dialect this transaction speaks, so a query builder can render for it. See the *_in methods on QueryBuilder.

pub async fn select(&mut self, sql: &str, params: &[Value]) -> Result<Vec<Row>>

pub async fn select_one( &mut self, sql: &str, params: &[Value], ) -> Result<Option<Row>>

pub async fn execute(&mut self, sql: &str, params: &[Value]) -> Result<u64>

pub async fn run(&mut self, sql: &str) -> Result<u64>

pub async fn scalar<T: FromValue>( &mut self, sql: &str, params: &[Value], ) -> Result<Option<T>>

pub async fn savepoint(&mut self, name: &str) -> Result<()>

A named savepoint, so part of a transaction can be undone on its own.

pub async fn rollback_to(&mut self, name: &str) -> Result<()>

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

Commit and release the connection.

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

Roll back and release the connection.

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.
