Implementations

impl SimpleConnection

pub fn drop_database(self) -> Result<(), FbError>

Drop the current database

pub fn close(self) -> Result<(), FbError>

pub fn begin_transaction_config( &mut self, confs: TransactionConfiguration ) -> Result<(), FbError>

Begins a new transaction with a custom transaction configuration, and instructs all the query and execute methods performed in the SimpleConnection type to not automatically commit and rollback until commit or rollback are called

pub fn commit(&mut self) -> Result<(), FbError>

Commit the default transaction

pub fn rollback(&mut self) -> Result<(), FbError>

Rollback the default transaction

pub fn wait_for_event(&mut self, name: String) -> Result<(), FbError>

Wait for an event to be posted on database
