Implementations

impl SqlFunction

pub fn new( function_name: String, input_types: Vec<PyDataType>, return_type: PyDataType, aggregation_bool: bool, ) -> Self

Trait Implementations

impl Clone for SqlFunction

fn clone(&self) -> SqlFunction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SqlFunction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl IntoPy<Py<PyAny>> for SqlFunction

fn into_py(self, py: Python<'_>) -> PyObject

👎Deprecated since 0.23.0: IntoPy is going to be replaced by IntoPyObject. See the migration guide (https://pyo3.rs/v0.23.0/migration) for more information.

Performs the conversion.

impl<'py> IntoPyObject<'py> for SqlFunction

type Target = SqlFunction

The Python output type

type Output = Bound<'py, <SqlFunction as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PyClass for SqlFunction

type Frozen = False

Whether the pyclass is frozen.

impl PyClassBaseType for SqlFunction

type LayoutAsBase = PyClassObject<SqlFunction>

type BaseNativeType = <SqlFunction as PyClassImpl>::BaseNativeType

type Initializer = PyClassInitializer<SqlFunction>

type PyClassMutability = <SqlFunction as PyClassImpl>::PyClassMutability

impl PyClassImpl for SqlFunction

const IS_BASETYPE: bool = true

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<SqlFunction>

This handles following two situations:

type PyClassMutability = <<PyAny 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 = PyAny

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