Struct PyTable

pub struct PyTable {
    lazy_provider: Option<Arc<dyn TableProvider + Send>>,
}

A table entry in the catalog.

Note: this object acts as a table provider for DataFusion.

Fields

lazy_provider: Option<Arc<dyn TableProvider + Send>>

Implementations

impl PyTable

fn __datafusion_table_provider__( self_: PyRefMut<'_, Self>, ) -> PyResult<Bound<'_, PyCapsule>>

Returns a DataFusion table provider capsule.

fn df(self_: PyRef<'_, Self>) -> PyResult<Bound<'_, PyAny>>

Registers the table with the DataFusion context and return a DataFrame.

Trait Implementations

impl Default for PyTable

fn default() -> PyTable

Returns the “default value” for a type.

impl PyClass for PyTable

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for PyTable

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = true

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

type BaseType = PyEntry

Base class

type ThreadChecker = SendablePyClass<PyTable>

This handles following two situations:

type PyClassMutability = <<PyEntry as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = <<PyTable as PyClassImpl>::BaseType as PyClassBaseType>::BaseNativeType

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
