Struct ConstraintManager 

pub struct ConstraintManager { /* private fields */ }

The goal of the constraint manager is to ensure all constraints are satisfied before we hand it off deeper into the stack. For now its taking on the null checks of RowData

Implementations

impl ConstraintManager

pub fn new( index_manager: IndexManager, vis_row_man: VisibleRowManager, ) -> ConstraintManager

pub async fn insert_row( &mut self, current_tran_id: TransactionId, table: &Arc<Table>, user_data: SqlTuple, ) -> Result<ItemPointer, ConstraintManagerError>

pub async fn get( &mut self, tran_id: TransactionId, table: &Arc<Table>, row_pointer: ItemPointer, ) -> Result<RowData, ConstraintManagerError>

Gets a specific tuple from below, at the moment just a passthrough

pub fn get_stream( self, tran_id: TransactionId, table: Arc<Table>, ) -> impl Stream<Item = Result<RowData, ConstraintManagerError>>

Provides a filtered view that respects transaction visibility At the moment this is practically just a passthrough
