Implementations

impl Program

pub fn prepared(&self) -> &Arc<PreparedProgram>

pub fn from_prepared( prepared: Arc<PreparedProgram>, connection: Arc<Connection>, ) -> Self

pub fn is_readonly(&self) -> bool

impl Program

pub fn step( &self, state: &mut ProgramState, pager: &Arc<Pager>, query_mode: QueryMode, waker: Option<&Waker>, ) -> Result<StepResult>

pub fn commit_txn( &self, pager: Arc<Pager>, program_state: &mut ProgramState, mv_store: Option<&Arc<MvStore<MvccClock, DynAllocator>>>, rollback: bool, ) -> Result<IOResult<()>>

pub fn abort( &self, pager: &Arc<Pager>, err: Option<&LimboError>, state: &mut ProgramState, ) -> Result<()>

Aborts the program due to various conditions (explicit error, interrupt or reset of unfinished statement) by rolling back the transaction This method is no-op if program was already finished (either aborted or executed to completion) Returns an error if cleanup operations (savepoint rollback/release) fail.

pub fn is_trigger_subprogram(&self) -> bool
