1.0.0 · Source§

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 PyPayload for PyUtf8Str

const PAYLOAD_TYPE_ID: TypeId

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

Safety Read more

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. Read more

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. Read more
