Struct TableFunctionHandle

pub struct TableFunctionHandle { /* private fields */ }

Implementations

impl TableFunctionHandle

pub fn create() -> Arc<Self>

pub fn set_name(&self, name: &CStr)

pub fn add_parameter(&self, type_: &LogicalTypeHandle)

pub fn add_named_parameter(&self, name: &CStr, type_: &LogicalTypeHandle)

pub unsafe fn set_extra_info( &self, extra_info: *mut c_void, destroy: duckdb_delete_callback_t, )

Safety

• Takes ownership of *extra_info
• destroy must outlive self
• destroy() frees extra_info

pub unsafe fn set_bind(&self, bind: duckdb_table_function_bind_t)

Safety

• bind must outlive self

pub unsafe fn set_init(&self, init: duckdb_table_function_init_t)

Safety

• init must outlive self

pub unsafe fn set_local_init(&self, init: duckdb_table_function_init_t)

Safety

• init must outlive self

pub unsafe fn set_function(&self, function: duckdb_table_function_t)

Safety

• init must outlive self

pub fn supports_projection_pushdown(&self, pushdown: bool)
