Implementations§
source§impl Transaction<'_>
impl Transaction<'_>
sourcepub fn rollback(self) -> Result<()>
pub fn rollback(self) -> Result<()>
Will consume and rollback transaction. You also can rely on Drop
implementation but it
will swallow errors.
sourcepub fn set_local_infile_handler(&mut self, handler: Option<LocalInfileHandler>)
pub fn set_local_infile_handler(&mut self, handler: Option<LocalInfileHandler>)
A way to override local infile handler for this transaction. Destructor of transaction will restore original handler.
sourcepub fn affected_rows(&self) -> u64
pub fn affected_rows(&self) -> u64
Returns the number of affected rows, reported by the server.
sourcepub fn last_insert_id(&self) -> Option<u64>
pub fn last_insert_id(&self) -> Option<u64>
Returns the last insert id of the last query, if any.
