    pub unsafe extern "rust-intrinsic" fn volatile_copy_nonoverlapping_memory<T>(
        dst: *mut T,
        src: *const T,
        count: usize

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

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

The volatile parameter is set to `true`, so it will not be optimized out unless size is equal to zero.

This intrinsic does not have a stable counterpart.
