Implementations

impl TableHeap

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, cid: CommandId, ) -> QuillSQLResult<()>

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 tuple with MVCC metadata meta, allocating a new page if the current tail page runs out of capacity.

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

where F: FnMut(RecordId, &TupleMeta, &Tuple) -> QuillSQLResult<Option<Lsn>>,

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

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

Overwrite the tuple metadata at rid without emitting WAL.

pub fn write_tuple_meta_with_lsn( &self, rid: RecordId, meta: TupleMeta, new_lsn: Option<Lsn>, ) -> QuillSQLResult<()>

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 vacuum_slot_if<F>( &self, rid: RecordId, predicate: F, ) -> QuillSQLResult<bool>

where F: FnOnce(&TupleMeta) -> bool,

Attempt to reclaim the tuple at rid if predicate returns true for the current metadata. Returns true when the tuple was removed.

Trait Implementations

impl Debug for TableHeap

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

Formats the value using the given formatter.
