Function core::intrinsics::atomic_xor

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

🔬 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

与当前值按位异或，返回前一个值。

通过将 Ordering::SeqCst 作为 order 传递，可以通过 fetch_xor 方法在 atomic 类型上使用此内部函数的稳定版本。 例如，AtomicBool::fetch_xor。
