Function std::intrinsics::atomic_nand

pub unsafe extern "rust-intrinsic" fn atomic_nand<T>(dst: *mut T, src: T) -> T where
    T: Copy, 

🔬 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

对当前值按位与，返回前一个值。

通过将 Ordering::SeqCst 作为 order 传递，可以通过 fetch_nand 方法在 AtomicBool 类型上使用此内联函数的稳定版本。 例如， AtomicBool::fetch_nand.
