Function volatile_copy_nonoverlapping_memory 

pub unsafe fn volatile_copy_nonoverlapping_memory<T>(
    dst: *mut T,
    src: *const T,
    count: usize,
)

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

Equivalent to the appropriate llvm.memcpy.p0i8.0i8.* intrinsic, with a size of count * size_of::<T>() and an alignment of align_of::<T>().

This intrinsic does not have a stable counterpart.

Safety

The safety requirements are consistent with copy_nonoverlapping while the read and write behaviors are volatile, which means it will not be optimized out unless _count or size_of::<T>() is equal to zero.
