Function core::intrinsics::atomic_umax_rel [−][src]
pub unsafe extern "rust-intrinsic" fn atomic_umax_rel<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
使用无符号比较将当前值设为最大值。
通过将 Ordering::Release 传递为 order，可以通过 fetch_max 方法在 atomic 无符号整数类型上使用此内联函数的稳定版本。
例如， AtomicU32::fetch_max.
