Function std::thread::local_impl::abort_on_dtor_unwind

pub fn abort_on_dtor_unwind(f: impl FnOnce())

🔬This is a nightly-only experimental API. (thread_local_internals)

Run a callback in a scenario which must not unwind (such as a extern "C" fn declared in a user crate). If the callback unwinds anyway, then rtabort with a message about thread local panicking on drop.
