Function std::intrinsics::volatile_copy_nonoverlapping_memory

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)

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

等效于适当的 llvm.memcpy.p0i8.0i8.* 本征，大小为 count*size_of::<T>()，对齐方式为

min_align_of::<T>()

volatile 参数设置为 true，因此除非大小等于零，否则不会对其进行优化。

此内联函数没有稳定的对应对象。
