pub struct TransactionBuilder<'a> { /* private fields */ }Expand description
A builder for database transactions.
Implementations§
Source§impl<'a> TransactionBuilder<'a>
impl<'a> TransactionBuilder<'a>
Sourcepub fn isolation_level(
self,
isolation_level: IsolationLevel,
) -> TransactionBuilder<'a>
pub fn isolation_level( self, isolation_level: IsolationLevel, ) -> TransactionBuilder<'a>
Sets the isolation level of the transaction.
Sourcepub fn read_only(self, read_only: bool) -> TransactionBuilder<'a>
pub fn read_only(self, read_only: bool) -> TransactionBuilder<'a>
Sets the access mode of the transaction.
Sourcepub fn deferrable(self, deferrable: bool) -> TransactionBuilder<'a>
pub fn deferrable(self, deferrable: bool) -> TransactionBuilder<'a>
Sets the deferrability of the transaction.
If the transaction is also serializable and read only, creation of the transaction may block, but when it completes the transaction is able to run with less overhead and a guarantee that it will not be aborted due to serialization failure.
Sourcepub async fn start(self) -> Result<Transaction<'a>, Error>
pub async fn start(self) -> Result<Transaction<'a>, Error>
Begins the transaction.
The transaction will roll back by default - use the commit method to commit it.
