Function atomic_load 

pub const unsafe fn atomic_load<T: Copy, const ORD: AtomicOrdering, const VOLATILE: bool>(
    src: *const T,
) -> T

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

Loads the current value of the pointer. T must be an integer or pointer type.

Safety

• If VOLATILE is true, this is equivalent to Atomic<T>::load_volatile. Refer to the documentation of that method for safety requirements.

• If VOLATILE is false, this is equivalent to Atomic<T>::from_ptr followed by Atomic<T>::load. Refer to the documentation of Atomic<T>::from_ptr for safety requirements.

The stabilized version of this intrinsic is available on the atomic types via the load method. For example, AtomicBool::load.
