pub unsafe extern "rust-intrinsic" fn atomic_cxchg_acqrel_acquire<T: Copy>(
    dst: *mut T,
    old: T,
    src: T
) -> (T, bool)
🔬This is a nightly-only experimental API. (core_intrinsics)
Expand description

Stores a value if the current value is the same as the old value.

The stabilized version of this intrinsic is available on the atomic types via the compare_exchange method by passing Ordering::AcqRel and Ordering::Acquire as the success and failure parameters. For example, AtomicBool::compare_exchange.
