Struct quaint::connector::Transaction

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

A representation of an SQL database transaction. If not commited, a transaction will be rolled back by default when dropped.

Currently does not support nesting, so starting a new transaction using the transaction object will panic.

Methods

impl<'a> Transaction<'a>

pub async fn commit<'_>(&'_ self) -> Result<()>

Commit the changes to the database and consume the transaction.

pub async fn rollback<'_>(&'_ self) -> Result<()>

Rolls back the changes to the database.
