Function std::intrinsics::atomic_fence_rel

pub unsafe extern "rust-intrinsic" fn atomic_fence_rel()

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

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

原子 fence。

通过将 Ordering::Release 传递为 order，可以在 atomic::fence 中获得此内联函数的稳定版本。
