Function std::intrinsics::atomic_and_acqrel[][src]

pub unsafe extern "rust-intrinsic" fn atomic_and_acqrel<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

Expand description

对当前值按位与,返回前一个值。

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