pub struct TransactionBuilder<'a> { /* private fields */ }
Expand description

A builder for database transactions.

Implementations§

source§

impl<'a> TransactionBuilder<'a>

source

pub fn isolation_level(self, isolation_level: IsolationLevel) -> Self

Sets the isolation level of the transaction.

source

pub fn read_only(self, read_only: bool) -> Self

Sets the access mode of the transaction.

source

pub fn deferrable(self, deferrable: bool) -> Self

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.

source

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.
