Module table 

DuckDB table functions: functions used in a FROM clause that produce rows and columns. DuckDB table functions: functions used in a FROM clause that produce rows and columns, e.g. SELECT * FROM my_func(1, 2).

Structs

BindInfo

An interface to store and retrieve data during the table function’s bind stage.

InitInfo

An interface to store and retrieve data during the table function’s init stage.

TableFunctionInfo

An interface to store and retrieve data during the table function’s execution stage.

TableInitData

The InitData shape shared by every #[duckdb_table_function]-generated VTab impl: a lazily consumed iterator of output rows, behind a Mutex so it can be shared across the worker threads DuckDB may execute the scan on.

Traits

TableRow

One output row of a table function: a tuple of values, one per column, in column order.

VTab

A DuckDB table function: produces rows and columns for use in a FROM clause, e.g. SELECT * FROM my_func(1, 2).

VTabLocalInit

A VTab that also produces per-worker-thread (“local”) init data, in addition to the query-wide init data every VTab already produces.

Functions

run_table_func

Pulls up to output.capacity() rows from init_data’s iterator and writes them into output, then sets output’s row count. Exhaustion is signalled by writing fewer rows than the capacity (including zero), which is what DataChunkHandle::set_len communicates to DuckDB either way.
