Implementations

impl TableHeap

pub fn try_new( schema: SchemaRef, buffer_pool: Arc<BufferManager>, ) -> QuillSQLResult<Self>

Creates a new table heap. This involves allocating an initial page.

pub fn insert_tuple( &self, meta: &TupleMeta, tuple: &Tuple, ) -> QuillSQLResult<RecordId>

Inserts a tuple into the table.

This function inserts the given tuple into the table. If the last page in the table has enough space for the tuple, it is inserted there. Otherwise, a new page is allocated and the tuple is inserted there.

Parameters:

• meta: The metadata associated with the tuple.
• tuple: The tuple to be inserted.

Returns: An Option containing the Rid of the inserted tuple if successful, otherwise None. Inserts a tuple into the table.

pub fn update_tuple(&self, rid: RecordId, tuple: Tuple) -> QuillSQLResult<()>

pub fn update_tuple_meta( &self, meta: TupleMeta, rid: RecordId, ) -> QuillSQLResult<()>

pub fn full_tuple(&self, rid: RecordId) -> QuillSQLResult<(TupleMeta, Tuple)>

pub fn tuple(&self, rid: RecordId) -> QuillSQLResult<Tuple>

pub fn tuple_meta(&self, rid: RecordId) -> QuillSQLResult<TupleMeta>

pub fn get_first_rid(&self) -> QuillSQLResult<Option<RecordId>>

pub fn get_next_rid(&self, rid: RecordId) -> QuillSQLResult<Option<RecordId>>

pub fn recovery_view(buffer_pool: Arc<BufferManager>) -> Self

Construct a lightweight TableHeap view for recovery operations. This instance uses an empty schema and does not rely on first/last page ids.

pub fn recover_set_tuple_meta( &self, rid: RecordId, meta: TupleMeta, ) -> QuillSQLResult<()>

Recovery-only API: set tuple meta without emitting WAL. Only used by RecoveryManager during UNDO.

pub fn recover_set_tuple_bytes( &self, rid: RecordId, new_bytes: &[u8], ) -> QuillSQLResult<()>

Recovery-only API: set tuple raw bytes without emitting WAL. If size mismatches, repack tuple area and update offsets.

pub fn recover_restore_tuple( &self, rid: RecordId, meta: TupleMeta, tuple: &Tuple, ) -> QuillSQLResult<()>

pub fn recover_delete_tuple( &self, rid: RecordId, txn_id: TransactionId, ) -> QuillSQLResult<()>

pub fn delete_tuple( &self, rid: RecordId, txn_id: TransactionId, ) -> QuillSQLResult<()>

Trait Implementations

impl Debug for TableHeap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
