Struct SeekFrom

pub struct SeekFrom { /* private fields */ }

The SeekFrom struct is used to specify a position in a stream for seeking operations. It combines a Whence value with an offset.

Implementations

impl SeekFrom

pub fn new(offset: i64, whence: Whence) -> Self

pub fn start(offset: u64) -> Self

Creates a new SeekFrom instance with Whence::Start and the specified offset.

pub fn end(offset: i64) -> Self

Creates a new SeekFrom instance with Whence::End and the specified offset.

pub fn current(offset: i64) -> Self

Creates a new SeekFrom instance with Whence::Current and the specified offset.

pub fn __str__(&self) -> String

pub fn __repr__(&self) -> String

pub fn __eq__(&self, other: Self) -> bool

pub fn __ne__(&self, other: Self) -> bool

pub fn __hash__(&self) -> u64

Trait Implementations

impl Clone for SeekFrom

fn clone(&self) -> SeekFrom

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<SeekFrom> for SeekFrom

fn from(seek_from: SeekFrom) -> Self

Converts to this type from the input type.

impl From<SeekFrom> for SeekFrom

fn from(seek_from: SeekFrom) -> Self

Converts to this type from the input type.

impl Hash for SeekFrom

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoPy<Py<PyAny>> for SeekFrom

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

Performs the conversion.

impl PartialEq for SeekFrom

fn eq(&self, other: &SeekFrom) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PyClass for SeekFrom

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for SeekFrom

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)]

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<SeekFrom>

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 doc(py: Python<'_>) -> PyResult<&'static CStr>

Rendered class doc

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

fn dict_offset() -> Option<isize>

fn weaklist_offset() -> Option<isize>

impl PyClassNewTextSignature<SeekFrom> for PyClassImplCollector<SeekFrom>

fn new_text_signature(self) -> Option<&'static str>

impl PyClass__eq__SlotFragment<SeekFrom> for PyClassImplCollector<SeekFrom>

unsafe fn __eq__( self, py: Python<'_>, _raw_slf: *mut PyObject, arg0: *mut PyObject, ) -> PyResult<*mut PyObject>

Safety: _slf and _other must be valid non-null Python objects

impl PyClass__ne__SlotFragment<SeekFrom> for PyClassImplCollector<SeekFrom>

unsafe fn __ne__( self, py: Python<'_>, _raw_slf: *mut PyObject, arg0: *mut PyObject, ) -> PyResult<*mut PyObject>

Safety: _slf and _other must be valid non-null Python objects

const MODULE: Option<&'static str> = ::core::option::Option::None

Module name, if any.

type AsRefTarget = PyCell<SeekFrom>

Utility type to make Py::as_ref work.

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

Returns the PyTypeObject instance for this type.

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

Returns the safe abstraction over the type object.

fn is_type_of(object: &PyAny) -> bool

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