DbTransaction

Struct DbTransaction 

Source
pub struct DbTransaction { /* private fields */ }
Expand description

Default ITransaction implementation wrapping an IAsyncConnection.

The connection is held in Option so commit / rollback can take it out by consuming the handle; subsequent savepoint/isolation calls on a consumed handle return EFError::Transaction.

Implementations§

Source§

impl DbTransaction

Source

pub fn new(conn: Box<dyn IAsyncConnection>) -> Self

Trait Implementations§

Source§

impl ITransaction for DbTransaction

Source§

fn commit( self: Box<Self>, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'static>>

Commits the transaction and consumes the handle.
Source§

fn rollback( self: Box<Self>, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'static>>

Rolls back the transaction and consumes the handle.
Source§

fn create_point<'a>( &'a mut self, name: &'a str, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'a>>

Creates a savepoint within the current transaction.
Source§

fn release_point<'a>( &'a mut self, name: &'a str, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'a>>

Releases (commits) a previously created savepoint.
Source§

fn rollback_point<'a>( &'a mut self, name: &'a str, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'a>>

Rolls back to the named savepoint, preserving the outer transaction.
Source§

fn set_isolation<'a>( &'a mut self, level: IsolationLevel, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'a>>

Sets the isolation level of the current transaction.
Source§

fn connection(&mut self) -> &mut (dyn IAsyncConnection + Send)

Exposes the underlying connection so save_changes() can reuse the ambient transaction’s connection.
