Struct rsfbclient::Connection [−][src]
A connection to a firebird database
Implementations
impl<C: FirebirdClient> Connection<C>
[src]
pub fn open(
cli: C,
conf: &ConnectionConfiguration<C::AttachmentConfig>
) -> Result<Connection<C>, FbError>
[src]
cli: C,
conf: &ConnectionConfiguration<C::AttachmentConfig>
) -> Result<Connection<C>, FbError>
Open the client connection.
pub fn drop_database(self) -> Result<(), FbError>
[src]
Drop the current database
pub fn close(self) -> Result<(), FbError>
[src]
Close the current connection.
pub fn with_transaction<T, F>(&mut self, closure: F) -> Result<T, FbError> where
F: FnOnce(&mut Transaction<'_, C>) -> Result<T, FbError>,
[src]
F: FnOnce(&mut Transaction<'_, C>) -> Result<T, FbError>,
Run a closure with a transaction, if the closure returns an error and the default transaction is not active, the transaction will rollback, else it will be committed
pub fn begin_transaction(&mut self) -> Result<(), FbError>
[src]
Begins a new transaction, and instructs all the query
and execute
methods
performed in the Connection
type to not automatically commit and rollback
until commit
or rollback
are called
pub fn commit(&mut self) -> Result<(), FbError>
[src]
Commit the default transaction
pub fn rollback(&mut self) -> Result<(), FbError>
[src]
Rollback the default transaction
