Function duckdb_table_function_supports_projection_pushdown 

pub unsafe extern "C" fn duckdb_table_function_supports_projection_pushdown(
    table_function: duckdb_table_function,
    pushdown: bool,
)

Sets whether or not the given table function supports projection pushdown.

If this is set to true, the system will provide a list of all required columns in the init stage through the duckdb_init_get_column_count and duckdb_init_get_column_index functions. If this is set to false (the default), the system will expect all columns to be projected.
