Function std::intrinsics::atomic_cxchg_acqrel_failrelaxed

pub unsafe extern "rust-intrinsic" fn atomic_cxchg_acqrel_failrelaxed<T>(    dst: *mut T,     old: T,     src: T) -> (T, bool)
🔬 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

Stores a value if the current value is the same as the old value. The stabilized version of this intrinsic is available on the std::sync::atomic types via the compare_exchange method by passing Ordering::AcqRel as the success and Ordering::Relaxed as the failure parameters. For example, AtomicBool::compare_exchange.
