Trait Implementations

impl Constructor for PyOSError

type Args = FuncArgs

fn py_new( _cls: &Py<PyType>, args: FuncArgs, vm: &VirtualMachine, ) -> PyResult<Self>

Creates the payload for this type. In most cases, just implement this method and let the default slot_new handle wrapping with the correct type.

fn slot_new(cls: PyTypeRef, args: FuncArgs, vm: &VirtualMachine) -> PyResult

The type slot for __new__. Override this only when you need special behavior beyond simple payload creation.

const __OWN_METHOD_DEFS: &'static [PyMethodDef] = _

fn __extend_py_class(ctx: &'static Context, class: &'static Py<PyType>)

fn __extend_slots(slots: &mut PyTypeSlots)

impl Debug for PyOSError

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

Formats the value using the given formatter.

impl Initializer for PyOSError

type Args = FuncArgs

fn slot_init( zelf: PyObjectRef, args: FuncArgs, vm: &VirtualMachine, ) -> PyResult<()>

fn init( _zelf: PyRef<Self>, _args: Self::Args, _vm: &VirtualMachine, ) -> PyResult<()>

const __OWN_METHOD_DEFS: &'static [PyMethodDef] = _

fn __extend_py_class(ctx: &'static Context, class: &'static Py<PyType>)

fn __extend_slots(slots: &mut PyTypeSlots)

impl MaybeTraverse for PyOSError

const HAS_TRAVERSE: bool = false

if is traceable, will be used by vtable to determine

const HAS_CLEAR: bool = false

if has clear implementation for circular reference resolution (tp_clear)

fn try_traverse(&self, tracer_fn: &mut TraverseFn<'_>)

fn try_clear(&mut self, out: &mut Vec<PyObjectRef>)

impl PyClassDef for PyOSError

const NAME: &'static str = "OSError"

const MODULE_NAME: Option<&'static str> = None

const TP_NAME: &'static str = "OSError"

const DOC: Option<&'static str>

const BASICSIZE: usize

const UNHASHABLE: bool = false

type Base = PyException

const ITEMSIZE: usize = 0

impl PyClassImpl for PyOSError

const TP_FLAGS: PyTypeFlags

const METHOD_DEFS: &'static [PyMethodDef]

fn impl_extend_class(ctx: &'static Context, class: &'static Py<PyType>)

fn extend_slots(slots: &mut PyTypeSlots)

fn extend_class(ctx: &'static Context, class: &'static Py<PyType>)

where Self: StaticType + Sized,

fn make_slots() -> PyTypeSlots

impl PyPayload for PyOSError

const PAYLOAD_TYPE_ID: TypeId = <PyException as ::rustpython_vm::PyPayload>::PAYLOAD_TYPE_ID

unsafe fn validate_downcastable_from(obj: &PyObject) -> bool

Safety

fn class(ctx: &Context) -> &'static Py<PyType>

fn try_downcast_from(obj: &PyObject, vm: &VirtualMachine) -> PyResult<()>

const HAS_FREELIST: bool = false

Whether this type has a freelist. Types with freelists require immediate (non-deferred) GC untracking during dealloc to prevent race conditions when the object is reused.

const MAX_FREELIST: usize = 0

Maximum number of objects to keep in the freelist.

unsafe fn freelist_push(_obj: *mut PyObject) -> bool

Try to push a dead object onto this type’s freelist for reuse. Returns true if the object was stored (caller must NOT free the memory). Called before tp_clear, so the payload is still intact.

unsafe fn freelist_pop(_payload: &Self) -> Option<NonNull<PyObject>>

Try to pop a pre-allocated object from this type’s freelist. The returned pointer still has the old payload; the caller must reinitialize ref_count, gc_bits, and payload.

fn into_pyobject(self, vm: &VirtualMachine) -> PyObjectRef

where Self: Debug,

fn _into_ref(self, cls: PyTypeRef, ctx: &Context) -> PyRef<Self>

impl PySubclass for PyOSError

type Base = PyException

fn as_base(&self) -> &Self::Base

Returns a reference to the base type’s payload.

fn create_static_type() -> PyTypeRef

where Self: PyClassImpl,

impl Traverse for PyOSError

fn traverse(&self, tracer_fn: &mut TraverseFn<'_>)

impl traverse() with caution! Following those guideline so traverse doesn’t cause memory error!:

fn clear(&mut self, _out: &mut Vec<PyObjectRef>)

Extract all owned child PyObjectRefs for circular reference resolution (tp_clear). Called just before object deallocation to break circular references. Default implementation does nothing.
