Method make_spawn_func

crates/vm/src/vm/thread.rs:540–545

Create a `FnOnce()` that can easily be passed to a function like [`std::thread::Builder::spawn`] # Note If you return a `PyObjectRef` (or a type that contains one) from `F`, and don't `join()` on the thread this `FnOnce` runs in, there is a possibility that that thread will panic as `PyObjectRef`'s `Drop` implementation tries to run the `__del__` destructor of a Python object but finds that it's

(self, f: F)

    /// as `PyObjectRef`'s `Drop` implementation tries to run the `__del__` destructor of a
    /// Python object but finds that it's not in the context of any vm.
    pub fn make_spawn_func<F, R>(self, f: F) -> impl FnOnce() -> R
    where
        F: FnOnce(&VirtualMachine) -> R,
    {
        move || self.run(f)
    }

    /// Run a function in this thread context
    ///
