Struct PyHandleProbe 

pub struct PyHandleProbe { /* private fields */ }

A closed control object over one Rust-produced Handle.

The handle comes from the real PyHandle::spawn path (HDL-13), never from PythonTask.spawn_handle(), so the contract suite observes a genuine direct Rust producer. The producer parks on a release gate, so a test decides exactly when the terminal state becomes observable without sleeping.

Two limits are load-bearing, not stylistic:

• It must never accept arbitrary Python work – no coroutine, awaitable, callable, future or producer function. Widening it to take one turns a contract fixture into a general async escape hatch, and every caller then depends on this module staying compiled into production.
• It must never be cited as a real producer’s oracle. Its timing is a release gate and its outcomes are three fixed cases, so it says nothing about when a real producer starts work or whether that work is abandoned when nobody observes it. Those belong to the producer’s own tests.

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 BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<PyHandleProbe>

This handles following two situations:

type Inventory = Pyo3MethodsInventoryForPyHandleProbe

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.
