Function std::intrinsics::atomic_xsub_acq

pub unsafe extern "rust-intrinsic" fn atomic_xsub_acq<T>(
    dst: *mut T, 
    src: T
) -> T

🔬 This is a nightly-only experimental API. (core_intrinsics #0)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

[−] Expand description

Subtract from the current value, returning the previous value. The stabilized version of this intrinsic is available on the std::sync::atomic types via the fetch_sub method by passing Ordering::Acquire as the order. For example, AtomicIsize::fetch_sub.
