Function core::intrinsics::atomic_xadd_relaxed [−][src]
pub unsafe extern "rust-intrinsic" fn atomic_xadd_relaxed<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
Expand description
加到当前值，返回前一个值。
通过将 Ordering::Relaxed 作为 order 传递，可以通过 fetch_add 方法在 atomic 类型上使用此内联函数的稳定版本。
例如， AtomicIsize::fetch_add.
