impl Constructor for PyGenericAlias

type Args = GenericAliasArgs

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.

fn py_new( _cls: &Py<PyType>, args: Self::Args, 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.

impl PyClassDef for PyGenericAlias

const NAME: &'static str = "GenericAlias"

const MODULE_NAME: Option<&'static str>

const TP_NAME: &'static str = "types.GenericAlias"

const DOC: ItemDoc

const ATTR_DOCS: &'static [(&'static str, u32, u32)]

Attribute name → database span, sorted by name. (u32::MAX, 0) is an explicit empty doc.

const BASICSIZE: usize

const UNHASHABLE: bool = false

const MEMBERS: &'static [PyMemberSpec]

type Base = PyBaseObject

fn assert_member_layout()

const ITEMSIZE: usize = 0

impl PyClassImpl for PyGenericAlias

const TP_FLAGS: PyTypeFlags

const INTERNAL_DOC: ItemDoc

Signature-bearing class doc. ItemDoc::NONE when the constructor has no signature.

const METHOD_DEFS: &'static [PyMethodDef]

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

fn extend_slots(slots: &mut PyTypeSlots)

where Self: StaticType + Sized,

impl PyPayload for PyGenericAlias

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

const PAYLOAD_TYPE_ID: TypeId = _

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

Safety

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

const NEW_REF_UNTRACKED: bool = false

Whether PyRef::new_ref skips auto-tracking this type in the GC even when it would otherwise qualify (has traverse, dict, or heap type). Such objects are created untracked and must be tracked explicitly if and when they can become part of a reference cycle. Used by FrameObject, which is created untracked and tracked lazily only on escape.

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 after tp_clear, so the payload is a cleared husk; implementations must not rely on its pre-clear contents.

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_ref_with_type_lazy_dict( self, vm: &VirtualMachine, cls: PyTypeRef, ) -> PyResult<PyRef<Self>>

where Self: Debug,

Like into_ref_with_type, but leaves the instance __dict__ unallocated until the first attribute write or __dict__ access. Only valid for types whose attribute protocol materializes the dict lazily via get_or_insert.
