Struct PyColumn 

pub struct PyColumn { /* private fields */ }

Single column of a fetched CCDB table.

Attributes

name : str Column name as recorded in CCDB metadata. column_type : ColumnType Storage type of the column values.

Implementations

impl PyColumn

pub fn name(&self) -> String

str: Column name as stored in CCDB metadata.

pub fn column_type(&self) -> PyColumnType

ColumnType: Declared storage type for the column.

pub fn row(&self, py: Python<'_>, row: usize) -> PyResult<Py<PyAny>>

row(self, row)

Parameters

row : int Zero-based row index.

Returns

object Value converted to a Python scalar.

Raises

RuntimeError If the requested row is out of range.

pub fn values(&self, py: Python<'_>) -> PyResult<Vec<Py<PyAny>>>

values(self)

Returns

list[object] All values converted to Python scalars in row order.

Trait Implementations

impl DerefToPyAny for PyColumn

impl ExtractPyClassWithClone for PyColumn

impl<'py> IntoPyObject<'py> for PyColumn

type Target = PyColumn

The Python output type

type Output = Bound<'py, <PyColumn 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 PyColumn

const NAME: &str = "Column"

Name of the class.

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for PyColumn

const MODULE: Option<&str>

Module which the class will be associated with.

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

const IS_IMMUTABLE_TYPE: bool = false

#[pyclass(immutable_type)]

const RAW_DOC: &'static CStr = /// Single column of a fetched CCDB table. /// /// Attributes /// ---------- /// name : str /// Column name as recorded in CCDB metadata. /// column_type : ColumnType /// Storage type of the column values.

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type Layout = <<PyColumn as PyClassImpl>::BaseNativeType as PyClassBaseType>::Layout<PyColumn>

Description of how this class is laid out in memory

type BaseType = PyAny

Base class

type ThreadChecker = ThreadCheckerImpl

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.

fn items_iter() -> PyClassItemsIter

fn lazy_type_object() -> &'static LazyTypeObject<Self>

fn dict_offset() -> Option<PyObjectOffset>

Used to provide the dictoffset slot (equivalent to tp_dictoffset)

fn weaklist_offset() -> Option<PyObjectOffset>

Used to provide the weaklistoffset slot (equivalent to tp_weaklistoffset

impl PyMethods<PyColumn> for PyClassImplCollector<PyColumn>

fn py_methods(self) -> &'static PyClassItems

impl PyTypeInfo for PyColumn

const NAME: &str = <Self as ::pyo3::PyClass>::NAME

👎Deprecated since 0.28.0:

prefer using ::type_object(py).name() to get the correct runtime value

Class name.

const MODULE: Option<&str> = <Self as ::pyo3::impl_::pyclass::PyClassImpl>::MODULE

👎Deprecated since 0.28.0:

prefer using ::type_object(py).module() to get the correct runtime value

Module name, if any.

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

Returns the PyTypeObject instance for this type.

fn type_object(py: Python<'_>) -> Bound<'_, PyType>

Returns the safe abstraction over the type object.

fn is_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
