Required Methods§

Source

fn begin<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Self::Transaction, DbErr>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Execute SQL BEGIN transaction. Returns a Transaction that can be committed or rolled back

Source

fn begin_with_config<'life0, 'async_trait>( &'life0 self, isolation_level: Option<IsolationLevel>, access_mode: Option<AccessMode>, ) -> Pin<Box<dyn Future<Output = Result<Self::Transaction, DbErr>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Execute SQL BEGIN transaction with isolation level and/or access mode. Returns a Transaction that can be committed or rolled back

Source

fn transaction<'life0, 'async_trait, F, T, E>( &'life0 self, callback: F, ) -> Pin<Box<dyn Future<Output = Result<T, TransactionError<E>>> + Send + 'async_trait>>
where F: for<'c> FnOnce(&'c Self::Transaction) -> Pin<Box<dyn Future<Output = Result<T, E>> + Send + 'c>> + Send + 'async_trait, T: Send + 'async_trait, E: Display + Debug + Send + 'async_trait, Self: 'async_trait, 'life0: 'async_trait,

Execute the function inside a transaction. If the function returns an error, the transaction will be rolled back. If it does not return an error, the transaction will be committed.

Source

fn transaction_with_config<'life0, 'async_trait, F, T, E>( &'life0 self, callback: F, isolation_level: Option<IsolationLevel>, access_mode: Option<AccessMode>, ) -> Pin<Box<dyn Future<Output = Result<T, TransactionError<E>>> + Send + 'async_trait>>
where F: for<'c> FnOnce(&'c Self::Transaction) -> Pin<Box<dyn Future<Output = Result<T, E>> + Send + 'c>> + Send + 'async_trait, T: Send + 'async_trait, E: Display + Debug + Send + 'async_trait, Self: 'async_trait, 'life0: 'async_trait,

Execute the function inside a transaction with isolation level and/or access mode. If the function returns an error, the transaction will be rolled back. If it does not return an error, the transaction will be committed.
