Struct TableStorage 

pub struct TableStorage<'a, 'txn, T: KVTransaction<'txn>> { /* private fields */ }

TableStorage provides CRUD and scan operations over a table backed by a KV store.

The two lifetime parameters serve distinct purposes:

• 'a: The borrow duration of the transaction reference
• 'txn: The lifetime parameter of the KVTransaction type itself

This separation is necessary to allow SqlTransaction to return TableStorage instances while maintaining proper lifetime relationships with GATs.

Implementations

impl<'a, 'txn, T: KVTransaction<'txn>> TableStorage<'a, 'txn, T>

pub fn new(txn: &'a mut T, table_meta: &TableMetadata) -> Self

Create a new TableStorage wrapper for a given table.

The table_id is obtained from table_meta.table_id.

pub fn insert(&mut self, row_id: u64, row: &[SqlValue]) -> Result<()>

Insert a row by RowID, enforcing primary key and NOT NULL constraints.

pub fn get(&mut self, row_id: u64) -> Result<Option<Vec<SqlValue>>>

Get a row by RowID.

pub fn update(&mut self, row_id: u64, row: &[SqlValue]) -> Result<()>

Update an existing row by RowID.

pub fn delete(&mut self, row_id: u64) -> Result<()>

Delete a row by RowID.

pub fn scan(&mut self) -> Result<TableScanIterator<'_>>

Scan all rows in the table.

pub fn range_scan( &mut self, start_row_id: u64, end_row_id: u64, ) -> Result<TableScanIterator<'_>>

Scan rows in the half-open RowID range [start_row_id, end_row_id].

pub fn next_row_id(&mut self) -> Result<u64>

Get the next auto-increment RowID, incrementing the stored sequence.
